Hi Jack! Contrary to what OpenSky has written above, they are absolutely nothing like Ebay and Amazon. Ebay and Amazon are highly rated companies that stand behind their products, their 3d party sellers and they are honest, caring companies. OpenSky, on the other hand, is one of the worst companies to deal with and have thousands of negative reviews. They hide behind excuses like, "We deal with tousands of independant merchants", and " We are soory for your troubles", but, in effect, they are a thieving, dishonest, poorly run company. They blame others for their shortcomings and never, ever, take responsibility for their poor performance. If you deal in any way with them, from being a buyer, to seller, to "independant merchant", you will regret it. OpenSky is all about stealing your money and giving you nothing, or selling you junk, most times poorly made. I am surprised they have not been shut down already. For me, I have complained to BBB and to the New York State Attorney General's office.In short, this company is a fraud...that is how they differ from Ebay and Amazon. Save yourself some grief and forget about this terrible company.
