Rockler’s running their winter clearance sale. You can get a T-track starter kit complete with 4′ of track, eight knobs, and eight t-bolts, for $12 — one of the better deals. This track probably won’t accept standard hex head hardware, but that’s easy to overlook since the price is so low.
They’re offering a lot of decent deals, so search hard and order quickly before they run out. Although Rockler’s tiered shipping rates are a bit high, you can offset it by purchasing lots of sale products. Warning: The website will add some sale products to your cart two at a time, but you can usually purchase a single unit without losing the discount.
