Amazon Smile is a great way to donate to your Lance P. Sijan Air Force Association chapter while you shop. You pay no extra on your purchase, so no, “do you want to round up your purchase, or donate a dollar to a charity”. You simply shop and pay no extra cost on your purchase and Amazon pays your Sijan chapter .5% of the purchase.
If you are a Amazon Prime member, What’s great about this is that you still receive all your benefits of being a prime member, nothing changes, except allowing Amazon to pay your Sijan chapter .5% of the purchase.
