The theory goes - and it may be part urban myth - is that you should not refrigerate eggs if the shops in your country don't. There'll have been no refrigeration at any point in the supply chain. Frost free fridges are extremely dry and will shorten the fresh lifespan of the eggs as the shell isn't perfectly air tight, and supposedly - this may be the part that's urban myth - can also damage the natural protective coating.

Certainly we've never had problems with eggs staying fresh in the cupboard for months, and would never put them in the fridge. Course it's not common to get that old, but we often go past the 2 weeks best before date. First thing to do with a new fridge is throw away the pointless egg tray. :)
