What bit confuses you?
If they bid £115 with a VAT-Reg seller, they pay them
£115 and reclaim £15 input VAT, then it's cost them £100.
But if they bid £115 with a non-VAT-reg seller,
they pay them £115 and it's cost them £115.
Are you sure it always works like that? I think I've seen
ebay offers from VAT registered sellers advising bidders that
they are bidding on an ex-VAT basis and that VAT will be added
to the amount of the winning bid. This would mean that a
VAT-reg buyer who bids £100 would pay £115 and reclaim £15,
so it costs them £100, while a non-VAT-reg buyer who bids £100
would pay £115 and that's what it would cost them.
The effect is that in the case of a non-VAT-reg seller, the
real cost to a buyer is the same no matter whether the buyer
is VAT-reg or not, and is equal to the amount of the bid noted,
while in the case of a VAT-reg seller, the real cost to the
two kinds of buyer differs, but the bid noted may be inclusive
or exclusive of VAT, and it is important for the bidder to be
aware of which it is.
Presumably the onus is on the seller to make clear what's what,
and in the absence of any mention of VAT, a non-VAT-reg buyer
should be entitled to assume that what they bid is what it will
cost them (i.e. no VAT will be added), and a VAT-reg buyer
should *not* be entitled to assume that the seller is VAT-reg
and so should *also* assume that what they bid is what it will
cost them (i.e. no VAT can be "subtracted").
