Well, it is a clearinghouse for RSD branded items from Indie Exclusives to leftover RSD stock. Only brick and mortar stores can participate. I'm mixed on whether its good idea to source that inventory in one place or if its a solution looking for a problem.
I say this because the initial sites that were open to sign up for it all run their own websites.. Conceivably with this inventory up for sale. Therefore they didnt need another site that is redundant to what they were doing. Flipside, if you didnt google search and find it already then the RSD brand may bring you to this site and introduce you to a store you didnt know.
They opened a few months before holiday and then abruptly did almost zero marketing for it.
One good thing about it, there are rules to the amount the stores can charge (just like when they sell anywhere else by the way), so you wont be gouged. Does that become a negative for these stores or is this the merch they cant sell at full price anyway?
Edit: Also, the sites now have to compete with all other stores for the lowest price, further eroding their markup.
