UPDATE: About 4 hrs. after my 12 pack of Dark Chocolate bars order was placed Walmart canceled my order saying they were out of stock and had no idea when the item would be in stock. Seems to me the advertisement was placed in error.
Did want the chocolate.
But I was able to get some Timberlands.
Rakuten (formerly Ebates) has some nice Cyber Monday cashback specials. I didn't spend much time going through the fine print on each offer, so please do before jumping. If you don't have a Rakuten account yet, grab a referral from the referral link thread for an additional $10 bonus to your cashback account.
Mint Mobile: Not quite as good as the one-day Black Friday offer, but $30 cashback on Mint Mobile SIM. (Stack with the $45 promo)
Tracfone, Simple Mobile, Total Wireless, and likely the other Tracfone companies, 15% cashback. (I think the highest we've seen in a year.)
QVC, 15% cashback-- pair with one of the $50-$60 Tracfone bundles (phone + year/1500/1500/1.5gb)
HSN: 7% cashback-- as above with Tracfone bundles
Motorola Mobility: 15% cashback-- pair with one of the phones that's been on sale for a while.
Bonus cashback for lots of other stores, too-- I've looked at cellphone related only.
