I have many purchasing regrets.
When you see something you like,...buy it.

Around 1979 (aged 11) in a boots in Ramsgate. (yes, a chemist used to have a vinyl section), I was torn between buying 4 singles or the "Bat out of Hell" album. I went with the singles.
Bought BOOH a few years later, and feel so ashamed of the singles I bought, I won't even name them.

1991 at a record fair in Coventry. A signed vinyl album , The Real Thing, by Faith No More. All members of the band had signed, and I think the seller was asking about £5. I swerved and regret

Chichester , around 1997. A shop was selling a Clarice Cliff china tea set for about £80. Was tempted, but swerved and regretted

I disengage, I turn the page.

Not on the same scale, but i know how you feel, we were close to buying a 2 bed maisonette re-furb in Bickley, Bromley for £61k in the early 1990’s, but decided to buy a flat in Sidcup for 10k cheaper!! We flogged that for a small profit and moved away from London because property was half the price, but I dread to think how much the maisonette in Bickley is worth now!!!

pussy pump for mrs KD to add to her fanny arsenal on a grubby weekend down brighton.
she wont entertain it now, claiming no knowledge or interest.
missed oppurtunity.

Kids,tired of being bothered by your pesky parents?
Then leave home, get a job & pay your own bills, while you still know everything.
