Excellent items at unbeatable prices, delivered right to your door---so you don't even have to deal with those clueless, failed social experiments at the store!

First of all, without telling you they AUTOMATICALLY plug in a 35% discount coupon to your customers, then charge you the additional fees for selling on their venue---seriously, WHO DOES THAT?
Want to see your order history? Well, you sure don't want to look under the "Orders" tab for that---they're not there!
After several months of inactivity, you will receive a personal phone call to find out how to give them even more money----since they're scraping after the 35% discount they're shoveling out. Instead of taking your concerns and their business model flaws into consideration, the customer service rep will talk over you, make excuses, tell you your order info is everywhere except the "Orders" tab---duh---and generally reinforce your feeling that you should never, ever, use OpenSky.

PS: As you can see from their reply below, they take no responsibility for such shady dealings beyond saying you can change the 35% discount. The thing is---which they refuse to grasp---is that you have to figure out that they have automatically g̶o̶u̶g̶e̶d set it for you in the first place.
Instead, it's assumed that we know this---and here I thought everyone knew that "$#*!*u*me" bit. Etsy doesn't do anything like that, neither does Amazon, neither does any other venue I've ever heard of---all of those business decisions are left up to the seller, where they belong.
But, if OpenSky already made the preposterous assumption that anyone outside of a Chinese gulag and seeking to actually make money on their site would offer a 35% discount, it begs the question,
What other money-shortening fields have also been filled in for us?
You're better off not knowing.
