We were on vacation a few years ago and stopped in at a thrift store. Found a brand new Coleman full size inflatable mattress for $10. We've used that for car camping and Scouting overnights (where we have to hike a really long 100' from the parking lot to the campsite LOL - we may be Scouts but we are suburban scouts!!)

Recently I picked up a brand new Gregory Baltoro 65 for $68.

Then, of course, there are all the items that I've repurposed for camping and hiking. For example, I bought  my wife a Fireball Advent calendar this past season and it had a plastic mini bottle of Fireball for each day. Washed a few of them out and they now will carry a variety of items when I backpack - hot sauce, seasoning mix (salt, pepper, and garlic powder), and - of course - a couple will be refilled with proper whiskey
