Prices of things on web sites

We're getting some new wheels & the web site for the shop we'll be going to pick them up from shows the wheels we want are the same price for all the different sizes of wheel in the colour we want. It is the base price for all the wheels of that style in that diameter, the other colours all go up a fair bit, like 10% when you go up in width, so it seems like it's a mistake. They do actually do mail order from their site so I could order 4 wheels (they only sell them as sets of 4 from the web site) at the price they say they are, only we want a staggered set, so I can't. This is a new colour for the wheel so it's likely to be a new addition to the site. I've had lengthy discussions with the chap at the shop about what sizes to go for & there is no problem getting a mixed / staggered set, it's just not on the web site. I'll be getting down to the price tomorrow with him but just wanted to find out first where I stand if it is a mistake & they should really be more then it's currently showing.

The thing is I'm fairly sure if I go into a shop & see something that's been priced accidentally too low they have to sell it to me at that price, but what's the deal with web sites?

I've seen the price on the web site, I could print screen to capture it but that could easily have been fiddled with so doesn't really mean much

Ah well, would seem I'm wrong there then! Must be one of those things your mum tells you like rubbing butter on burns, she was amazed when I gave her some cream actually designed for burns the other day....

Turns out the price difference was actually down to the non inclusion of rim protectors with the wheels we were looking at, no mistake.
