I went to see my mate last week, her & her DP have 2 kids, 2.5 and just over a month.
She told me her DH gets really annoyed because her mum keeps buying things for the kids which are in the sale. Clothes from Next or M&S, but in the sale - he thinks it's cheeky and threw a bag of stuff in the bin 
She didn't seem to think it was a problem, I said if they weren't any good she should've taken them back and exchanged stuff, not thrown perfectly good brand new clothes in the bin because they were reduced... she got a bit annoyed with me, but I just think it's such a waste, am I wrong?
