Negotiating options when ordered online?

hello,

First time posting long time tundra fan. I plan on buying a 2021 tundra assuming its the last year of the V8. Ive been playing around with the 'build a tundra' tool on the Toyota website. When you build a truck it gives you an invoice with a price. Ive never purchased a new truck before or ordered one off the website. Im interested in getting an SR5 with the SX package or an SR5 with the TRD sport package. Neither of those trucks are widely available in my area so I was thinking in order to get one I may need to order it direct.

My question is is this price they give you on the 'build a truck' tool firm or can you negotiate this? If so who would you negotiate with?

Thanks

 

Did a little reading online and sounds like when you order from the "factory" you actually need to order through a dealer and there are some advantages and disadvantages to the process
