Here’s another hot idea for that Buy $30, Get $10 Instant Savings promotion at Amazon. Obviously, most of you will mix and match with other items in the promotion; however, if you do want 42 toothbrushes, you should be able to pick them up for just $0.46 each. Note that I do say “should,” because I am not sure if the $10 discount will trigger since your total goes under $30 with the subscription discount. You may need to add an extra item if it doesn’t work, so watch closely during checkout to make sure the $10 comes off. Colgate Extra Clean Full Head Toothbrush 6-packs – only $19.19 for SEVEN 6-packs (42 toothbrushes; $0.46/toothbrush) after subscription discount and instant savings!
