can u mix 2 different anker discounts?
Anker discounts
In my experiments - NO.
e.g. I was thinking of some longer cables so they did some discount codes on 3 of them and when I tried to use them all with multiple items it only seemed to use either the 1st code or the largest discount code, but certainly not all. So that tends to give the most to gain if you got Amazon Prime to avoid the multiple postage costs.
