just a question, has anybody ever bought the biiiig display case thing with 48 boosters in it for hundreds of pounds? if so, is it worth it? what chance is there of getting loads of uniques?

Actually, if you buy a sealed case from the right source, you can save up to 40% or more from the cost of buying them individually.

Also, with a case you usually get around 8 uniques.

Finally, you can defray the costs by selling extra figs that you don't want or need on ebay. Sometimes you can sell about half your case and pay for the cost of the whole thing, or even make a bit of a profit.
