They should have made a country pack, the shirts with the emblem 40 tokens, that way If you only whant a shirt you buy that shirt, If you whant all, you buy the pack, that way more people would buy.
With the current prices, i now it is too high comparing with those of the clubs, but i bet that most people Will only buy one of the options.

But it is just my opinion

Other thing they could do, is that whend a team is eliminated, a 24h discount to buy the things of that country.
