For some time, drugstores have been trying to bribe shoppers to spend by promising post-purchase saving coupons (good for use on the next or a future purchase). Now, supermarkets are getting into the act. We see these offers at Shaw’s and Stop & Shop this week.

But be careful: You’ll need to be organized and save those print-out coupons in a safe place; they are like money. Furthermore, you’ll need to remember to use the coupons quickly, because they usually expire in a month or less. Plus, many of the manufacturer’s rebates require store receipt, rebate form and UPCs. That’s a lot of ways you can mess up the process and miss out on extra savings. Still, the offers can be tempting.

For example, from today-Thursday (July 31-Aug. 6), Shaw’s is offering $5 off your next purchase when you buy $20 in P&G products as well as an extra $15 off your next shopping trip when you spend $30 or more on participating General Mills and Unilever products. There’s also a form for a $10 rebate for buying various Kellogg’s products.

Also, from today-Thursday (July 31-Aug. 6), Stop & Shop/Milford also has some savings for shoppers who buy multiple products, including four boxes of General Mills cereal for $6 and four 12-packs of Pepsi products for $10. Furthermore, Stop & Shop fliers have strips of four $1 doubler coupons to use when you spend at least $15. Additionally, shoppers can save on Edy’s ice cream 1.5-quart containers priced at $1.99 (limit 3) and sweet corn, 12 ears for $1.99.

From Sunday-Saturday (Aug. 2-8), Market Basket has a number of good specials. Gallons of store brand milk (whole, 2%, 1% and skim) are $1.99. Cooked deli ham is $2.99 a pound. There are in-store coupons to use on Kellogg’s cereal (as well as the $10 rebate from Kellogg’s). Plus, there’s a Barilla penne value pack of eight 1-pound boxes for $6.99, and heads of romaine lettuce for 79 cents.

Finally, the CVS and Walgreen drugstore chains have some good deals this week.

From Sunday-Tuesday (Aug. 2-4), CVS has four 12-packs of Pepsi products for $8 after $4 back in Extra Bucks. Also on those three days, there are many good offers on back-to-school products, including some for free.

From Sunday-Saturday (Aug. 2-8), Walgreens has various Kellogg’s cereals at two boxes for $3, after $2 back in Register Rewards. And there’s a flier coupon for store brand 500-count aspirin or 100- to 125-count enteric aspirin for $1.99 (limit 3).

Always try to use manufacturers coupons to save even more.
