I work at thrift store and have had tons of perfectly new, clean glass Tupperware-type containers with sturdy snap-on plastic lids come through our donations. Enough that nearly every employee bought some and don’t need any more, plenty go out on the shelves regularly - they get snatched up fast tho! Good to go early in the day when you can.
I suggest you purchase whatever you really need to start, but keep checking in your local thrifts occasionally to supplement! Sometimes you might find stainless steel ones, and lunchbox kits with glass insert tubs, great for on-the-go prep meals.
