Good riddance, at 1x Hawaiian you guys were getting ripped off to begin with. Note Amazon pays ~6% to affiliates:

I would suggest using ebates or fatwallet to get 4% CB in the categories that pay cash back. In other categories, support your favorite Amazon Associate. For example, Frequent Miler has an Amazon link here:

http://boardingarea.com/blogs/frequentmiler/shop/

Or you could support the UR mall comparison page which also has an Amazon link.

Regardless of what portal you use, you can also get 5x UR + 5%-7.5% cash back when you shop at Amazon as follows:

1) buy $500 VanillaVisa GCs at OD with Chase Ink (nets 5x UR less 1% fee)
2) upgrade your VanillaVisa GCs to BestBuy GCs via PlasticJungle (6% discount plus YMMV 2.5% TopCashBack)
3) upgrade your BestBuy GCs to Amazon Kindle GCs in store
4) load Amazon Kindle GCs to your Amazon account (they will automatically be used for your Amazon purchases)
5) use ebates or fatwallet to get another 4% CB at Amazon when you shop in limited categories, or support your favorite Amazon Associate in other categories
