It's been a while since I flew Delta - I was a Silver Medallion member before, but don't hold any status now. It turns out I've 111K miles in my account that I'd like to use to buy products/gadgets etc in the Delta Marketplace.

However, I can't seem to see *any* products listed in the Delta Marketplace site. Is this because I no longer have any status with Delta? If that's the case, how can I spend the 111K miles anywhere?

I see there are other sites (http://www.skymilesshopping.com/) that may allow me to buy products with my miles. Is this legit, or will I have to give a significant cut of my miles to these guys?

Any advice?
