Ok, it is noon ~ and all the guesses are in, so here are the results:
Toothbrush: 4.99 with 4.99 rebate (tax only) = 0.25
Nail Polish: 2.99 with 2.99 rebate (tax only) = 0.15
Lipstick: 4.99 with 4.99 rebate (tax only) = 0.25
Lady Speed Stick: 2.00 with 2.00 rebate (tax only) = 0.10
Speed Stick: 2.00 with 2.00 rebate (tax only) = 0.10
Toothpaste: 4/$10 with 5.00 rebate = 5.00 minus 3 x 0.75 coupons = 2.75 + tax = 2.89
GRAND TOTAL: $3.74
The winner is Megan! Her guess was $3.62 - an amazing 0.12 within the correct price! Great job Megan!
Since she doesn't use lipstick or nail polish - I thought I'd donate them to a local Children's Shelter that takes in youth who are in abusive homes and collects items like this to give out to them when they arrive.
Thanks, everyone, for playing along!
