I've got a TON of coupons expiring today (way to leave it til the last minute), so I'm going to be making a trip to london drugs to stock up on a bunch of free, or nearly free items.

I just spent the last couple hours sorting out my coupons by item, then going through flyers to find the best prices (remember... london drugs price matches!).

Once I got all the coupons into groups, I taped them together with a little note saying how much all the coupons are worth together, and where I am price matching and for what price. This saves a LOT of time at the checkout. Also note that to do price matches at LD, you have to have your items rung up at customer service, not at the regular checkouts.
I took out the pages from the flyers I needed and circled the items I am price matching. Make sure that when you do this that at least one page of the flyer you're taking has the flyer dates on it, which is usually the first page.
I then organized the groups of coupons by which isle they're in, and sorted them to match my list. eg: Purex & windex are the first on my list, so they're on top of the coupon pile. Hair dye is last, so it's on the bottom. Again, saves you time :)
