cheaper than dirt is really inconsistent with their price gouging. it seems anything they can't keep in stock due to high demand and low supply, they just jack the price. but other items that are in even higher demand but still a somewhat steady supply, they keep their prices quite low, and sometimes are even lowering them further.
ie: AR accessories. even though these are selling like crazy, and they run out of stock of these occasionally, they haven't raised the prices. AR magazines though, my god they nearly quadrupled the prices of these. 15rd handgun mags are flying off the shelves, often getting a mass shipment in and selling out within minutes, yet they still have the lowest prices on these.
I say just do your research. some places may be better and/or cheaper than other places. and those same places may be worse and/or more expensive than others with other items, similar to CTD.
