HP Chocolate Frog Question

I was looking up what kind of treats you can get from wizarding world and I saw there is a Chocolate Frog tin that comes with 5 cards in it as opposed to the regular chocolate frogs that just come with 1. I wanted to know if the tins always have the same 5 cards in them or can they be different. Should I buy regular chocolate frogs with the tin to increase my chances of collecting more of the cards or can I just buy the tins?
