$10 off $50 at Amazon Groceries
Not exactly camping related, unless you’re ordering oatmeal and granola in bulk, but Amazon.com has an online grocery store that sells non-perishable food at pretty good prices. I’m not sure if I want to get 5 boxes of cereal all at once, but you can get $10 off a $50 order with coupon code MEAL1000 (enter code in the “promo code or gift certificate box at checkout, no mention of when the coupon expires).
