For the budget conscious, carpet tiles can be picked-up very cheaply:

If time is not a concern, post COVID, I could probably bring two or three (surplus to our needs) to an RTE at some stage. Wont be much cheaper though, as it'll cost a schooner of dark ale.
One of my isolation projects, cleaning out the garage, involves listing surplus items on eBay, some of you will be suprised what junk some people we pay $$ for, and it's easier (and cheaper) than putting them out for the hrad rubbish collection.
A set of old tyres under the house off the old EL Falcon. When I got some new tyres for Helen's EL many years back, kept the oldies as they were still in RW condition (thought they be good trailer tyres), 12 years later, I don't think I'll be using them, put 'em out for the hard rubbish collection, they would not take 'em ($40 charge - WTF), put 'em on eBay, got $40. That's an $80 turnaround in my favour, or two or three tanks of ULP, thanks very much.
