The fact that you can reach all my ETSY stores from this top level program (TheAgateTrader.com) might make you think you were dealing with a big well integrated system but there are two problems:
When you make your first purchase in an ETSY store you are asked to define a password. If you go to other stores and make purchases you will have to define a new password in each store. Use the same password for all the stores and you won’t have to remember which store has which password. It’s easy to change passwords.
When you are in an ETSY store and have items in your shopping cart be sure to pay before you leave that store.
