Yes, this one had that too! If you zoom into the very first picture you can see the dates on the tins. I should have mentioned that because its a trick, like you said.

I think that its the same shop as you were at. I'm pretty sure its a franchise amd there are locatjons all over Portugal and maybe Europe. I saw the same shop in Lisbon I think, but it actually might have been Porto.

All in all, its a cool idea but the prices were insane when you think about what you're buying. I guess it works on some people... like me 😅😆

But then, I tried it so that others don't have to I suppose haha

🤷‍♂️
