I'm glad you found the means to get your needs filled, and managed to get a good deal out of it!
I also agree with you about absolutely loving the fact that they use glass (that's big for me as well)! Likewise, I have had nothing but quality product from them, and their shipping has always been accurate and very fast. So there's some things that they are very much on the right track with!
There's just certain things (as I've mentioned above, or previously) about this particular approach that leave me wanting. Another of which is related directly to Inawera, and that's that they don't show/denote specifically which flavor is from what grouping: Yummy Classics, Wera Gardens, Koncentrat, etc.
Now, granted, for those that are willing to do a little legwork, it's not hard to figure out where some of these fall. But with others, many "titles" overlap groups, so by RTS not defining which group (Inawera family) they're from, you have to get your next batch from RTS if you want the exact same thing. And I feel this is intentionally done, especially when you see the other tactics in place and actively used.
I dunno. Maybe it's just me. But I would rather "reward" other vendors that use a more direct approach in pricing (with a modest sale), who list things with a more complete picture (looked at Cap VC, and it didn't even say if it was v1 or v2, just "diacetyl free"), and maybe even pay a little more.
All in all, at least they ship quality product, that's well packed, and quickly. That's more than we can say for some. For me, the rest is more of an "ethics vote" as far as the dollar goes (obviously).
EDIT: I find it interesting that you had the USPS option for a single 120ml, but I didn't for 90ml's. Geographic difference, or more shenanigans? The world may never know... /*chuckles*
