Hoarding is usually bad. Stacks of newspapers piled high...too many salt and pepper shaker...a small path to the bathroom...but there is one thing that is worth hoarding for a while...
Case in point. We bought Justin's mother a giftcard for Christmas. Not just any gift card, but an X-Box Live Microsoft points card. 4000 points = $50. It doesn't work. The store won't do anything for us because we don't have the receipt, so we have to deal with Microsoft. Of the two, Microsoft has been a lot nicer to deal with.
