I think that envelopes have suffered from extreme price inflation. I thought envelopes were, like, free last time I bought them. Or maybe a dollar or something. But I bought some today and the smallest pack they had was almost seven bucks! Seven bucks! For envelopes! I don’t get it. Prices of envelopes should be going down. Maybe more research needs to be put into more efficient envelope creation technology, to reduce the cost to produce them. Or perhaps lickable adhesive is getting more expensive?
