There's no better way to save money when shopping than to combine promotions. Online, when I shop, I often combine free shipping offers with percentage-off discounts. In the grocery store, I try to use coupons on sale items. This morning, at Shopko, I used two different promotions to whittle down my bill from $42.39 to $7.39. First, I used a $10 off a $40 purchase coupon I had received in the mail for signing up for Shopko's free loyalty card program. Then I used a free $25 gift card I received for picking up a prescription at Shopko's pharmacy. (I had asked them about a month ago to honor a competitor's pharmacy coupon.) To pay the remaining $7.39, I used a $10 prepaid Visa card I received as part of a rebate offer earlier in the year.
