US /(CAN) WTB Playstation 1 Memory Cards in lots of 10 (non-Sony brand okay)

First off, as discussed in message thread I am having a hard time to finding memory cards for my PSX in working order. Local is not an option for me so I decided to reach out.

I'm looking to buy PSX (Playstation 1) memory cards in lots of 10. They do not have to be Sony brand but I will not buy the new generic Memory cards. I only bought 5 of them and all 5 them turned out not to work.

I'm looking to buy from sellers that are willing to test the cards and give some kind of DOA warranty on them.

Brands I am willing to buy are:

Sony | Pelican
InterAct | GameStop Brand
MadCatz | Some Clear Generic (tested)
Performance | Performance 2X cards

I prefer to buy from the US but willing to buy from CAN if the price is good. Please be willing to accept PayPal for payment, and if you need to know if I can be trusted just look up 'lockar001' on eBay for my feedback.

Thanks!
