Exhibit A – a Ziplock brand quart size freezer bag (10.1¢/bag) after approx. 1 month of moderate use:

Exhibit B – a Target Up & Up brand quart size freezer bag (6.8¢/bag) after I-don’t-remember-but-at-least-six-months of moderate use:

In my experience, the edge of the closure on Ziplock brand bags is always the first part to fail. The fused edges on the Up & Up line keep the zipper closure intact well past the point where the rest of the bag has failed due to puncture or abrasion. This feature isn’t only on their freezer bags, it’s on the whole product line, even the dinky little snack bags.
