OEM Roof Rack Price and Weight capacity

Just about ready to pull the trigger on the OEM Roof Rack - has this gone up in price with the release of the 3rd gen? It seemed like it used to cost $250 with shipping, but now it seems like its about $300+ with shipping. Just want to make sure there isn't some type of obscure deal or discount I might be missing out, like for example purchasing the roof rack from some dealer in New Mexico or North Dakota for $100 off.

It also seems like there are two different weight limits listed after searching here and on google. One is 75 lbs and the other is 100 lbs. Are these just conservative, untested limits posted by Toyota, and is the capacity limit much higher than that?

 

I always put at least 100 pounds on mine with two kayaks. No issues too report.

 

I got mine back in 2010 for $199 from a dealer in Dallas
