This is something that I've shared about briefly before. Using coupons in a way that honors God is very important to me. You can still stack sometimes and definitely save a lot of money. Coupon guidelines have gotten a lot stricter since Extreme Couponing came out, but there are still lots of ways to save both time and money while using coupons.
When stacking coupons (using a manufacturer and a store
coupon) at Target, Rite Aid, and CVS always double check to make sure
that they don't indicate "no other coupon may be used with this coupon"
or " may not be combined with other offers" or "only one coupon valid
for items". Many manufacturer coupons are starting to state this in the fine print,
so they cannot be stacked with store coupons. I'll start making note of
them when I do my weekly matchup's on the website. Let me know if you
have any questions about this.
