You could email customer services to see if they'd be kind enough to honour the lower price as you very recently bought the items at a higher price before going around the houses reordering and returning. Of course, they don't have to refund the difference, some companies do though, but there's no obligation.
Could do. Then again, it's easy enough to take out the one item which hasn't been reduced further, slap on the free returns label, and put it in the outgoing post rack at work.
Not odd at all.
