sweets, after re-reading your post, we *MAY* be saying the same thing. This is the process...
1. Buy beer on 3F
2. At check out (and i haven't done it in a few months and as you said, the language is confusing), you pick a proxy service. Belgium in a Box used to the go to for me, but they went belly up during the pandemic. Etre Gourmet is the other option.
3. 3F ships the box to Etre Gourment for a nominal fee (the last time it was $9.99) as these places are literally a few blocks from each other.
4. Etre Gourmet contacts you when they receive the box (typically a week or two).
5. Once received, you pay for shipping to the US from etre, however, they will hold your box for up to three months and let you fill it with other goodies from their website to maximize your shipping costs.
6. My last box came with 16 bottles that included three bottles of 3f Zenne (once a whale), five bottles of 3 shelfies including Gueze AG, OG Gueze, and Kriek, six bottles of Cantillon, and two bottles of De Cam and Fabriek (a lambic maker I've never had).
7. Grand total came to $22 bucks a bottle after everything.
8. Now that sidepour is having a coronary, let me know if there is anywhere in the US you can get any of those bottles for that price even if they're very similar to the sours Lost Rhino is producing.
