Our stores are relatively new, so pretty okay on cleanliness.
Last year we got all our stocking stuffers there. Son is a Scout, so we got him all sorts of little things that would come in handy but hardly be used (and not worth spending a bunch of money on) - zip ties, bungee cords, multi-tool, travel tissues, travel sunscreen, key chain/can opener, phone charger, etc.
Last year we also went to two DT stores grabbing up wire mesh trash cans that make EXCELLENT garden cloches for sprouting plants. De-greaser. Our four large, handled soup mugs came from there (and are going strong after 4 years of use). A mini-spatula. Plastic colander. Comet cleanser.
We went on a road-trip last summer and all our travel items came from DT including First Aid kit stuff (generic benadryl, gas-ex, tums, ibuprofen, tylenol, immodium), a small plastic lidded container to use as a car trash can, duct tape, antibacterial travel wipes, ear plugs (because someone DOES NOT snore, pfft).
