iRAG 36W Dual USB Quick Charge 3.0 Car Charger $6.74 with coupon code, Amazon, free shipping $6.74

Hello Folks,
Found a decent deal on QC 3.0 charger with two (2) QC 3.0 Ports… 8.99, but $6.74 after 25% code IRAG2500

I believe you cannot combine this code with other promo codes; for example i tried to buy Anker Roav Camera (that also had a promo code), but amazon wouldnt apply both codes to cart. So I placed two separate orders, so I could avail both codes
