Shopping portals can provide a great way to earn extra miles — if you’re making online purchases, there’s no reason not to double-dip by going through one to boost your earning rate. Earning rates through these portals are known to change pretty much constantly, and American’s portal is now offering some limited-time elevated earning rates for a variety of business and office-supply merchants.

From today, November 5, to Wednesday November 11, you can take advantage of increased AAdvantage miles-earning rates with a handful of business-related vendors. Note that the elevated earning level for each merchant will be available for 3-4 days during this period. The first batch will be available from November 5 to 11:59pm ET on November 8, while the second group is available from November 9 to 11:59pm ET on November 11.

According to TPG’s latest valuations, American AAdvantage miles are worth 1.7 cents apiece. With the highest earning rate offered through this promotion — 16 miles per dollar through vendor 4 Inkjets — you’d net about 27 cents per dollar. If you’re a small business owner in need of some new office supplies and you have a particular award redemption on American or a partner airline in mind, this could be a good opportunity to stock up.

Don
Don’t forget to use Chase Ink to pay for Office Depot charges.

Also, keep in mind that you can “double dip” by taking advantage of credit card category bonuses. For example, if you pay for an Office Depot purchase with a Chase Ink Plus card, you’ll earn 5 Ultimate Rewards points per dollar in addition to the 5 miles you’ll earn per dollar as part of this promotion. Considering that TPG values Ultimate Rewards points at 2.1 cents each, you’re essentially getting a 10.5 cents-per-dollar return in addition to the 8.5 cents you’ll get through the portal for a total of 19 cents worth of points for each dollar you spend. Not too shabby!

Ultimately, the timing here couldn’t be better — it’s a great way to hit year-end spend for your business while earning lots of extra miles in the process. You can invest in 2016 supplies now but have the expenses hit your 2015 bottom line!
