Is it just me, or did the US Grand Slam set up unrealistic expectations on how many miles to earn through shopping portals?

not just you, I think my therapist Glen Morangie has almost helped me overcome US Air's decision not to run a GS.

Edited to add: Terms for US Air portal promo currently: receive 300, 500 or 1,000 bonus miles when you spend $150, $250 or $500 online through Dividend Miles StoreFront.

I refuse to shop on the mileageplusshopping.com site until they post my points from 8/31! I spent $323.99 at eBags.com to take advantage of an incredible 18 miles/$ offer. I'm now at 76 days since the purchase, should I call Chase? I know the T&C say it could take 60-90 days, but I've never seen points/miles take so long to post.

Send an Email to: contactus@mileageplusshopping.com. Lately they have been responsive to inquiries (including to an eBags issue that they resolved within a week).

500 miles for $250 in spend? On the Black Friday Week? Seriously? Everybody understands this is like a 2% price drop right? When everybody and his brother are looking for 20%, 30%, 40% off deals...

Not impressed by this offer. Ignore.

For comparison, lets say you spend $750 on a debit card attached to a new Citi checking account, you could earn 15K or 30K miles. 30,000 miles. Not 250 x 3 = 750. Now that's an offer.

It's a shopping portal, you can still spend on any CC (or debit card in your example) and get 500 bonus miles for $250 ON TOP of the x miles/$ you get from the portal anyway. These aren't mutually exclusive deals.
