It is not "my" product. Iam only a guy which has bought some crates. So if you want a direct answer if this is possible you have to contact the producers in the netherlands. Their shop is available in english, the link is in the first post.
But anyway, i can send a mixed crate to you (the producers wont do that), but as i said the shipping fee is "hardcore".
Might think about it, definitely sounds interesting... Ill ask my friend (who owns a gas station) to see if he would want to maybe carry it for a bit. I wouldn't have the funds to order anything more than the bottle caps right now. lol. But either way, sounds cool.
