If any of you are thinking that cashiers at Jewel have started paying more attention to what coupons you are using and on which products, you are right.  There has been a lot of discussion on the boards about this and here is a response from Jewel on this issue (grateful thanks to Barb at CW):

[are these printables we’re talking about?]  Not necessarily—there are some pretty crafty individuals out there that have manufactured their own hard copy coupons—not printables. That is why it has become so cumbersome for our poor cashiers. There are so many more steps involved in the transaction process now because we have been burned sooooo many times.

You can share with your readers that although it may seem as though the checkout process is taking longer than expected, please be patient with the cashiers, as they are simply doing their job to protect the company from those few people that have tried to cheat the business by presenting fraudulent coupons. Due to advancements in technology, we have learned that these new fake coupons do not beep, and therefore our checkers require a little intervention prior to scanning every coupon without question. In order to continue to pass along deals, savings and promos to our shoppers, we need to have the means to achieve that—which means more careful checkout procedures. We have not changed anything in our coupon policy, but need to ensure that the coupons that we are accepting are fitting those criteria in our stated policy to a T.

Of course, I prefer this Trib article.  Note the last paragraphs and imagine bin Laden sitting in a cave clipping coupons.  And how the hell could they even get home delivery? And what paper has the high value coupons?  so many questions…
