Living in France for a long time now we've had oour fun with the various sellers and suppliers.
We've been using Causeway4x4 for the last few years and they've been very good. No flashy sites, just tell them what you need and they'll tell you. Shipping can be done how you want. Transport goes wrong sometimes and that is when you learn the good and the less good ones. You don't need worries about the seller on top of that..
I go over every year a few times and combine those trip with stocking up. Also, long suffering friends in Emsworth are the Arjan
's Post Office and warehouse for me and that works very well. In fact, 1 item we got was cheaper to go over, get it ouselves than buying it here around the corner...
Good luck.
