No-deposit wooden pallets are often found in wholesale stores and establishments and warehouses that handle larger stocks. In any case, you might want to try out some of your local stores if you can get their no-deposit wooden pallets for free. Most of them discard these cheap wooden pallets anyway since the sturdy (usually with deposit) ones go back to whoever owns them. Here are some things you can actually do with them.

Storage platform. Yes. The obvious use for this one is pretty much the pallet’s innate function. While you may not have a forklift to help you ferry things around, you can simply use it to store things off the ground.

Firewood. Stacked and stored pallets (lots of them) have been causes of fires before and are known to be fire hazards. This just points you to two things - 1) don’t be a pallet-fiend and store them all and 2) use them as firewood. However, make sure that the wood used is the plain, untreated kind. Many pallets today use treated wood like plywood

Woodwork patch. If you have to patch up some woodwork around the house, pallets can serve just as well as your hardware-bought lumber. They’d even work for picket-fence work.

Pallet crafts. Pallet crafts have been around the Web for quite sometime now. You can pretty much do different woodwork with these things - tables, work counters, benches, etc… Check out these pallet shed - sheds that use pallets as main building components.

Skateboard obstacles. This one occurred to me last as I remembered playing Tony Hawk Pro Skater games. They do use pallets as skateboard obstacles once in a while. Usually for manual tricks.
