Exchanging Sale Items?

I bought something in the sale and I wasn't happy with it so it's currently in the post making it's way to Lovehoney and I have asked that it be exchanged for a similar item which is also in the sale. Seeing as how the sale ends tomorrow does that mean I will be paying full price for it?

I wouldn't have thought so but just use live chat to flag it up to them and ask the question?
