i never really had a pick and mix, Not good value for money
If it's pay-by-weight (and get a nasty surprise at the checkout), I agree - but the "all you can fit in a cup for X amount" was a game changer!
If it’s the company I buy from, they usually do 10 scoops that you get to choose yourself from about 25-30 different things. However since C19 their having supply issues so are selling premixed ‘Jellies’, ‘fizzies’, etc.
Ahh! Choosing a number of scoops from a range is what I was expecting, yes. Don't know if it is the same company, but am willing to forgive the pre-mixed thing if it is down to coronavirus issues - I'll try and remember to have another look once things are back to normal.
@LEELULUMPKIN - Ooh, I'd forgotten the thread where the husband spent £99! I went with a company called Posted Sweets - mainly for its variety. A lot of the websites I looked at didn't do chocolate footballs, which were a pick 'n' mix staple of my youth!
@PyongyangKipperbang - Hehe, will do! Some of the sites I looked at said that their cola bottles were Haribo ones, so there are definitely places that will sell you them in bulk!
@TheFormerPorpentinaScamander - When my order arrives, I'm happy to post pics of what 100g worth looks like (for the gobstoppers, I'm only expecting a couple!) Agree about postage costs though 
@listsandbudgets - That sounds like an excellent homeschooling opportunity! Making a mental note of the idea for when my DDs are older...
