Here are my tips from the last triples:
Tips for Triples
HT official policy is they will double/triple up to 20 coupons per household per day. So you can make one trip each day....for a total of 3.
I also do use the time for things that hardly ever go on sale - DS loves YoBaby yogurt so I buy a bunch with the .50/1 , Egglands Best too- I try to trade for higher values since they have gone on sale at Lowes twice and HT never. Alot of stuff gives overage so I will use overage to pay for stuff like I mentioned above. I'll donate the overage stuff I don't need.
Also think seasonly - it is about to be summer so we'll have good sale on condiments. So don't buy ketchup, mustard, mayo, relish, BBQ sauce, marinade etc unless it is on sale. Chances are it will be free during regular sale after doubles.
Also you may want to start emailing companies - plenty of time to get coupons. Check out the "Contacting companies to complain or cheer" thread. I LOVE non insert qs during triples because it means I can find the product easily!
