To me the issue with going into town is normally I want one thing, and I want to be quick.
Going to the big car park (which is at one end of town) takes ages longer than if I could just park on the streets and run into the shop.
Our town changed almost all the 30 minutes spaces on the streets into disabled spaces. Which I totally understand why, however it's easier to order on line now.
There used to be a line of 6 30 minute spaces that were just off the town centre and you'd always get a space there within once circle of the town - which was quicker than going into the multi-storey.
They changed all but one into disabled. I don't normally bother trying for the single one I could use, but on the times I have tried it, I haven't been able to get it.
I do think the council was right to change them to disability spaces, because the people that do need them can get them and the multi-storey, whereas it does have the ground floor as disabled spaces, someone in a wheelchair would have to go a long way round to avoid the stairs and someone who struggled to walk would find it too far from most of the shops.
I wouldn't mind paying £1 for 30 minutes park, but it's the convenience for what I'd use town for now.
If I was going in for a longer Christmas shop, then I'm very happy to use (and pay for) the multi-storey.
So I don't think it would make a difference to me.
It's cheaper to park all day than take a bus for me and a child into town (from 6 minutes away) anyway.
