they do that all the time. I bought a Dewalt XRP drill kit with the whole setup, drill, case, charger, 2 XRP batteries, refurbed for 130. 2 days after it arrived it was down to 63 BUCKS.... I called and they credited my card 66 back so I ordered a second one and made 3 bucks
Those drill kits go for around 300 new and batteries alone are 100 for 2.
Now hours after I bought it, it went up to 215, then a few days later it's down to 130 again with free slow shipping.
Pays to watch their sales and be patient, also price match em on the phone if it drops right after you get whatever it is ya want.
As soon as price drops to stupid level again I'm buying 2 more, they have almost exactly same warranty as new and looked brand new.
