The simple answer to your question is that you have bought these seeds too early and they will all go sprout an take over the world!
The more complicated answer is keep them in as cool and dark but frost free a space as possible, for as long as possible and set them to chit a month to six weeks before you intend to plant. If they have started to sprout rub them off and store as above. We all tend to buy our potato seed a bit early as they tend to get scarce at planting time. Keep a eye on them from time to time
Hope this helps
