Not for Big Macs, but if you’re interested I’ve been collecting Canadian grocery price data over the past couple of years here: https://grocerytracker.ca/

This is great! I would love something like this for Hong Kong. The prices here are very volatile due to special offers, etc.

Any plans to add other countries?

If I had unlimited time I would love to. Unfortunately I can’t see it expanding beyond Canada anytime soon though.

You should probably sort the store/city selector dropdown alphabetically.

Agreed on the stores. Cities/locations should be sorted by distance from your location.

Oh wow! I've been looking for something like this. Thank you.

Have you had any hassles from supermarket chains?

No, but I’ll admit that is my biggest hesitation in promoting it beyond what I already do. Walmart has the most aggressive blocking (in general, I don’t think specifically directed at my site) and I haven’t been able to get new data from them since October I think. Otherwise haven’t had any issues.

Big +1 to this. A medium fries at Canadian McDonald’s is now $5, it’s madness!

I got a 10 piece McNuggets meal the other day. Cost $15. Wild stuff.

Yeah, I used to stop at McDonald's on my way home from a big grocery run and stopped when I saw the fries there cost more than the giant bag of frozen fries I had just bought...

Wow. $2.74 CAD in the UK.

I feel they’ve shrunk too but ymmv.

Seemed to me the same size box, less fries. I was there recently.

AFAIK UK pricing is national?
