There are different ways it could work out. You guys are making up your plot. How about this.
If you did call them and complain about one of your orders being cancelled and enough people made noise then they would think twice about cancelling the single reel they promised.
Whereas, if no one makes any noise, then they figure that they can just go ahead and cancel all orders.
In my case they cancelled other items along with the deal on a single order, I wanted to know why? They then informed me of the cancelling of all orders of the mispriced reel and that I could just reorder, obviously at the higher price.
Story can be molded however we like. Fact is, let's just see if we do get that one reel, long time between now and end of July/August. Really it's no big deal, what's a few bucks when I can be doing this
