Are you sure they bought it from big w?? Sorry focussing on an off topic thing here, but every item has the same barcode on it, but it will register at a different price depending on the store they bought it from. Im not sure where you live, but is it possible it was bought from a smaller shop maybe and did actually cost her more?? I know the last SS i did i went over budget coz i was buying from a small toy shop who up price everything - and i didnt want to receiver to think "gee they didnt meet the mark" because what i bought WOULD have been less from a Big W or Kmart IYKWIM???
