That could be the problem..The cups are nice looking. But they are stuff companies give away for free etc. It's not enough. Ideally the shop should sell gadgets for cars (like cell phone holders, chargers) crypto stickers, crypto gadgets, crypto covers for cell phones..lots of stuff related to cryptos. As it grows it could also sell tech stuff, computers, cellphones etc. Bigger stuff.
I know I'd love to buy crypto gadgets, a t-shirt, an eth-watch, stuff like tht..like small things for a Steem or two.
