That app looks great. I am in the process of setting up a store to sell Steemit Tshirts. I want to get some more merchandise and work out a step by step guide for how people can purchase before doing a post about it.
I might not get around to launching the store till OB2 gets released. We will see.
Found your store! http://bazaarbay.org/@eroche Looks like great products so far. It's so easy for people to be able to buy but having more tutorials definitely won't hurt at all for those who are new to spending their crypto at all, and within the Steemit community, that is a lot.
