The costs of these products alone can add up to hundreds and thousands of dollars a year.
But we met an "extreme couponer" who gets all those items for free! She even gets the drug store to PAY her!
Not only does extreme couponer Claire Williams get all her drug store products for free, often she makes money on them.
"These are melatonin I actually made money on each one of these, I made $1 per bottle I bought" boasted Claire.
Claire says the trick is combining drug store deals with the manufacturer coupons, both of which come together in the Sunday paper.
"The Arnicare is a fantastic deal this week, it's normally $10.99, but it's on sale for $5.99. When we spend $5.99 we actually get $5.99 back from Walgreens in the form of register rewards which is dollars you can spend at Walgreens. But things get better because I already have a coupon for this week. We'll be making $2 to buy this" explained Claire.
Claire points out, contrary to popular belief, you can almost always combine drug store coupons, and they rarely limit you to just one.
But she says the trick to the big pay-off is planning.
"Because the best deals each week may not necessarily be on your shopping list that day. If you can get deodorant free this week get 5 of them and don't buy deodorant for 6 months or a year" said Claire.
So, after picking up a few more of Claire's weekly deals, we headed to the register to cash in.
And sure enough, $10 back!
But don't confuse these register rewards for more coupons.
These register rewards can be used for anything at Walgreens.
Which means you can now go back and get the stuff you need for free.
"You do it in multiple transactions so you're spending very little out of pocket" said Claire.
Now, if coupon clipping isn't your style, Claire makes it easy on her blog at saving-money-plan.com.
She posts a printable list each week, with what you can stock up on for free.
