how much were cassettes in the 80s and 90s? did they get cheaper as the 90s went on?

I worked in audio retail back then, there is no exact retail price as it depended on what deal the store got and what sale price we put on them. Retail, there were prices for single, three packs and boxes of 10 for sale, wholesale we’d sometimes buy shipments of 5,000 at a time to get discounts. Overall though, lower end tapes were $1-2, higher-end Chrome $2-3, metal $3-5. And $5 was a lot of money in the 80’s…Prices didn’t really go down or up as time went on. From what I remember, tape sales just faded away as CD’s and burning your own CD’s came along and then MP3’s. 

Good answer. Cassettes pretty much blow.

I remember prices coming down on certain brands towards the end of the 90s we were getting great deals on Sony Metal tapes for like $10. But  Maxells XLIIS's were typically consistent at $20 a box though they would occasionally go on sale.

$2 to $5
