Senior trip Shopping

I went on a shopping trip and used my coupons to buy all of the things I need for senior trip next weekend. (sunblock, shampoo, conditioner, toothbrush, TONS of snacks). I spent about $45 on about $85 worth of items. Almost a savings of 50% on all the things I needed. I felt short of crazy carrying my huge coupon binder around the store haha! I purchased the items in 3 transactions. In the first one I forgot to hand the coupons to the cashier and to my surprise he just handed me $2 cash instead of going back to take it off the register. I found that very weird but I appreciated it. I also picked but the paper which only had one smart source insert in it.
