It depends on where I shop. When it comes to food, I tend to use a hybrid of the Disney reusable bags (both Parks RPET and forced Store 'dustcover' reusables) and thicker plastic bags, which are the norm where I am. However, I don't like the long handles the Parks bags have, because of the fact I tend to carry them by hand and not sling them over my shoulder as the design intends. Not to mention that the quality of both bags are questionable at times, since I already have two Parks reusables that have had their graphic layer tear at the handle area, and the Store dustcovers are also hit or miss with build quality, since I often see loose threads on the inner stitching.
