I too, like SIG products a lot, and while I was reading this thread I realized I haven't placed any orders with Tower since they stopped carrying SIG. Meanwhile I have placed a few orders with other on-line retailers, not only for SIG but other brand products as well.

Not sure what kind of market share SIG has in the RC market, but if they have a broad and loyal customer base, this move will cost Tower money since they will loose sales for other brands as a byproduct of discontinuing SIG since most people will not split orders to take advantage of free shipping with on-line retailers. Again, that's assuming SIG has a commanding presence in the market, otherwise really doesn't matter for Tower.
