i have a yellow one as well. i bought it at the local liqueur store when they first came out but it was an empty version.
i don't remember if there was a choice between full or empty when i bought it.
there are several of the purple and yellow ones show up at the local flea market every month in the summer from the same vendor.
i can't remember what he was asking, but it seemed reasonable.
they did, however, show up month after month [and this has been ongoing for several years now] except for this year when the flea market was cancelled due to the virus.
i don't know if he has a bunch of them, or nobody has any interest.
