Linking purchases

[Lady Frostbite]

I know that linking to live auctions that are not your own are not allowed on site, but are you allowed to link Etsy stores that you have purchased items from? I know it blurs the line between promotion and simply citing. Sure, linking to Walmart for a particular doll is okay, but I wondered about places like Etsy?

(I purchased a really nice g4 sticker hence I ask)
