My last stop on the day I spent in Sendai was at the Mint Sendai store. This store is located just west of Sendai Station on the first floor of a shopping mall called "E BeanS".
There's a series of elevated walkways on that side of the station so it's possible to walk from the station to the mall without being at street level.
Here's a photo of the shop itself:
As you can (hopefully) see from this photo, the shop isn't very big. As I mentioned in my write up of Mint Shinjuku, Mint's mall shops tend to have limited space and limited inventory. This store was very similar to Mint Shinjuku in that it mostly had recent releases. The one thing though that this store had that Mint Shinjuku didn't was team issued cards for the Eagles. I ended up spending about 5400 yen here entirely on Eagles team issued cards although about half of that were cards I picked up for Ryan. I believe that this store is one of the few card shops in Japan that Ryan has not been to yet.
I'm pretty sure that this shop takes credit cards although I paid cash for what I bought.
Here's a map showing the store's location:
