Ive been watching a specialty fan on their sight for a few days, waiting to decide if it was the correct model for my custom application. I viewed it on sept 1 and printed off the page for reference. The day after I then received a email about their weekend labour day promo going on with a 10% off discount code. Hurray I thought. I log into the site, and check out the fan. And low and behold it went from $519 to $557 in a matter of a day. A magical 7% increase. Wow looks like it just turned that 10% discount into a useless 3% discount. All of the other items on their site did the same thing.
