Accounting question

[Ruth Morley]

I think this is an accounting question rather than a gnucash question but
here goes.
 ordered a household item which I then returned. The original purchase went
into Expenses:Household and then I got a rebate.
Now should I put the rebate amount into the expenses:household or should I
set up a new income category which is for instance Income:Rebates.
I think the former would make more sense to me but may not be correct.
Ideas??
