Thanks to Winglets747 for pointing this out to me. I can find no link in AS, DL or PCR portals for eBay shopping. Should've probably said YMMV.

It seems that evreward's data maybe out of date, had this another time with Giftcertificates.com being listed as in Thankyounetwork for months when it wasn't an available merchant.

There still are some offers out there, and ultimately it should still be cheaper to get them this way than paying par at the NWA shopping portal.

Mypoints is offering 5 points per dollar for October, Thankyounetwork (just checked) offers 1 TYP/$1 spent and there seem to be other offers for cash rebate sites.

Keep checking, with eBay ramping up the marketing, maybe the airline mile portals will come back.
