With the (temporary?) demise of AGC cb portal buying, I'm wondering if anyone has thoughts or experience on reselling goods bought through a portal on eBay/Craigslist. My thought is that the combination of no sales tax on certain e-commerce sites + free shipping + free returns (+ extended return policy via amex) + coupon codes would allow one to at least break even on the purchase price of a good with resale potential and then retain the points.
