Will have a scout about and if all else failes will have to buy from the US and pay 20% or so imprt tax.
Not if you keep your order round the $100 mark, you won't.
I've been ordering direct from Brigade Games for about four years now and not once have I been hit by French customs. Dunno if my method works out for you, but what I do is wait for Lon to do one of his occasional 10% discount sales, order about 120 dollars's worth of figures - which works out at $108 once the discount has been applied, and Bob's yer uncle - or rather mine in this particular case. If you really need a lot of stuff, then place several separate orders and keep them all below the $110 mark. Postage will be more expensive that way but it's still cheaper than paying import duties.
I must have placed 15 to 20 orders over the past four years and have always slipped under the French customs' radar.
