The Alaska MileagePlan shopping portal is offering 2X miles for purchases at eBay today. You can also earn an additional 1,500 miles for purchases of $500 or more through the portal with their holiday promotion.
By spending $500, you would earn a total of 2,500 miles or 5X per dollar spent on eBay. Currently there aren’t any eBay Bucks promotions to stack this with, but maybe this increased payout will stick around for awhile.
Note: The standard eBay portal restrictions apply: “Not eligible for purchases on eBay gift cards, eBay Vehicles, eBay Real Estate, Heavy Machinery, Bullion and Charity items. Eligible on Winning Bid and Buy It Now purchases up to $5,000. Not eligible on unpaid items with eBay.”
