money-saving monday {6.1}

again, couldn't resist the alliteration. anyway... i wasn't planning on going to walgreen's this week. but i read a post about a deal on a hair dryer, which i desperately need, so i stopped on my lunch hour.
deal was found here: common sense with money

first transaction:
original price of hair dryer = $19.99
sale price = $12.99
rewards coupon = $10

second transaction:
gripe water = $10.99
after coupon = 99 cents + tax

summary:
total @ full price = $30.98
total paid = $13.98
total savings = $17.00
