Diffrence between Model 7596 and 7596A

Getting close to pulling the trigger on my second Taco, a 2012 Dual Cab V6 4WD with 6ft bed and while comparing bids from various dealers I noticed that one dealer listed the model as a 7596 and another listed the model as a 7596A. Does anyone know the difference -or- significance of the "A". I inspected the quotes from both dealers and they are identical except the dealer that quoted the "A" model include all weather floor mats. I also did some google searches can't find anything. Does anyone know the difference?

Thanks!

 

I'm not 100% sure but, I believe the letter following the model number indicates a dealer price change for that model year. Most of the time that means a price increase.
