If you ordered from Ehobbyasia, does it tae much longer to get in the UK, or do you pay more postage for quicker, because i dont know anything about foreign sites, cuodl anyone fill me in?
their 3-5 day postage is always on time, when you dont take in consideration customs, and is relatively cheap to say somewhere like rsov. 
Now a 'namsofter. I have an M72 L.A.W. for sale for 110 posted, PM if interested.
As 101 says, the big unknown when buying from abroad is UK customs. How quickly your parcel arrives seems to be largely dependent on whether the Customs Officer got laid last night 
With the current exchange rates and import duty / VAT / ParcelForce add-ons you rarely save more that a few quid these days.
If you need something in a hurry then get it from a UK supplier.
All my airsoft guns come from there at it always arrived in 3-5 days. Mind I live the Netherlands so it doesn't have to cross the water.

how much is postage for things roughly?
All very well saying "buy in UK", but if you can't get it in the UK...
Was like that for me getting KA midcaps for my Sten. I didn't pay for the fast delivery (I was going to be away), but it came quickly anyway.
