First one is unfair to them. Aussie is valued at one non plus a sorbet so the other sorbet is not needed. The drink me eat me set is valued at one non. So overpay their side.
Second one is overpay their side as well. The sunback, which some like I value at a Sunjewel, is worth 5-6 nons, whereas your side is worth a non (drink me eat me) + 3 sorbets at value, though the Bengal could go for less, so about 2 nons in total. So they're overpaying by 3-4 nons c:
Third one not really sure but I'm positive a non is worth a little over a thousand c$ so I think 2000 alone would be fair for the drink me eat me set. But keep in mind no one really sells pets for c$. [1040]
Overall the second one is one I'd take c:
