Grateful, so you have come across this practice before? I've been doing the exchange at HD for several
years now, and this is the first time I have been shorted. I thought this was something new.

Basically I've never done exchange not once but it was all over the internet some time ago about them
short changing people on exchange bottles. I've always bought my bottles outright, empty.
