Most plastic items in dollar stores should be avoided. Some non-branded products may be alright, but it’s hard to distinguish just by looking at the package. Unfortunately, in dollar stores, you will most often find plastic bags so thin that even the slightest breeze could tear them apart.
That’s not very reassuring when you have to carry trash in them. If you don’t want to collect trash from all over your driveway, spend more money on quality brands. On the other hand, If the packaging lets you feel the individual bags’ thickness, it might be a good buy.
