Rode my bike miles into the city. To find out the shop itself has been closed for years. Even the info touchscreen thingy said it was open and it's definitely been closed since 2019. I'm not happy that google maps says this is open 24 hours just because it's a website now. That's bunk.

Traveled to Boston and walked into this little store. I bought this bracelet for $80, but this happened literally less than a week after I bought it. Don't know what to say now, very concerned about the quality.
