Does anyone remember the original price of football shirts from the 2004-05 season?

Hi everyone

I’m trying to figure out what the release price was for football shirts back in the 2004-05 season. Specifically, I’m curious about the Chelsea kits from that year (made by Umbro), but info on any kits from that season would be helpful.

From what I’ve read, shirts around that time might’ve been in the £40-50 range for adults, but I’d love to hear from anyone who remembers buying one back then or has an old catalogue, receipt, or ad to confirm.

Any insight would be appreciated—thanks!
