Here's my vaccine experience with Pharmeasy as a vaccination center. This might be helpful to fellow BHPians hence the informative and detailed post:
As I had contracted Covid back in April (was asymptomatic and recovered as of 1 May). This meant that I couldn't take the vaccine till approximately 1st week of August. Nonethless, I kept visiting the cowin website to book appointments for friends and family. I thought that by the time I need to get an appointment for myself, I'd have mastered the art. Oh boy, was I wrong!
Don't get me wrong, I managed to book a total of about 50 appointments (friends and family) in a span of 3 months, but I was finding it tough for myself as I wanted to go ahead with Sputnik. The reason behind Sputnik being the (arguably) better efficacy, easier availability (haha, not so much after all), and most importantly, the shorter interval between two doses that would aid my travel process (work-related).
I could see fairly good availability for Sputnik just a week before I had to book an appointment, but I don't know what happened later. Slots went full left, right, and center! I made up my mind to get it done anyhow, and booked and appointment in Pune, even if it meant travelling a few 100 kms to and fro. Meanwhile, I got my anti-body test done and since it was much higher than normal, I was advised to take the shot in August and not last week of July (84-90 days per se).
While checking the slot notification window on telegram (yes, there are subscriptions that notify you of slot availability in your region, based on the choice of vaccine (atleast that was the case with Mumbai/Navi Mumbai/Thane back then). There was a ticker on top that said Pharmeasy offers vaccination at two centers in Mumbai, (both, at their offices in Ghatkopar and Bandra). I signed up on the website and almost booked an appointment, but held back for the moment since I wasn't sure how credible they are. Ended up checking with my friend and a fellow BHPian whose batchmate works with Dr Reddy's (authorised to supply Sputnik in India) and received a confirmation that the same batchmate got the jab at the Ghatkopar centre itself. A sigh of relief later, registered to get the shot in the upcoming weekend. Registration et al was simple, the only confusing thing was the lack of an option to head to the particular vaccination page from the brand's official website.
Pharmeasy has divided the slots into dose 1 and dose 2, and depending upon availability, they also offer covishield. I booked an appointment for a slot between 11am and 12pm on 1 August. Reached there at 10.55 and was pleasantly surprised to see a nice and fairly clean parking lot (a must for us BHPians, right?) Situated on the first floor, you're greeted by a registration desk, where one has to check for your name in a list and sign next to it. Next up, they check and confirm your credentials with the ones filled on the site. Once done, you're handed a form to fill (attaching an image below) along with a token number. You get into their corporate office and sit at the work desks while you wait your chance. They were experiencing some network issues that particular day and hence there were a good number of people lined up waiting to get their jab. The form handed over to you has to be filled by yourself or the nurse sitting at one of the tables there, followed by which you have to make the payment (they accept cash and GPay). Gpay was a bit glitchy for me but the guy sitting at the payment counter took me into confidence that if he receives double payment, a simple call to the said number is all that's required for a refund of the excess amount. Since there was a delay from their side to administer vaccines, they were kind enough to offer water and tea to everyone waiting. There were 3-4 rooms where one person each could get a jab at one time. Once the technical issue was resolved, things sped up and I was done with the jab in about 10 minutes. They check your id proof here so don't forget that (they were kind enough to accept a soft copy when I forgot to carry the hard-copy during the second dose though).
They have multiple small cubicles (kinda like the office meeting rooms) where 4 people can wait at a time until the mandatory half an hour wait period is up. The nurse that administers you the jab also writes the entry and exit time on the paper token and it has to be handed over to security before you leave. They also have a small photo cut-out sort of thing for those who don't want to miss a celebratory photo-op.

Photo-op anyone?

The parking for bikes as well as cars
I had a slight fever the following night and a real bad headache that had me getting up thrice in the night (real bad for someone lime me who can otherwise sleep through an earthquake). After breakfast the next day, I was back to normal. Surprisingly, I didn't have any pain or heaviness in the arm except for the first 5 minutes after taking the jab.
Booking the appointment for the second dose was rather flawless too. Since I had no visible effect during the day when I took the first dose, I decided to travel by bike for a change. As last time, parking was good and the so was the overall experience. I reached a bit late this time, 11.50 for a 11-12 slot, but the experience was good and I was in and out within an hour (including the mandatory half an hour waiting). Got the message confirming my vaccination within 2 minutes of taking the jab.
TLDR:
Pharmeasy charges Rs. 1,350 for a single shot, which is about 200 more than the government prescribed rate.
Is it illegal? I'm not sure, but BHPians are free to pitch in on this.
Did I have a good experience? Yes!
Will I recommend it to others? If you're in or around Mumbai and want a shot of Sputnik, absolutely!
Reliable service backed by friendly folks, just make sure you're fine paying the extra dough.
This reminds me, they've also launched this service in Delhi and Gujarat.
For people wanting to go this week, I checked with them in person yesterday for a friend and they said they're outta stock for the first dose of Sputnik until September.
