If you're thinking about heading towards Portland or Seattle, you might want to consider going through Tacoma. Edensaw Woods has a location there and they can get most of what they have in Port Townsend there overnight. There is also Architectural Hardwoods in Tacoma. Plenty of good places in Portland (and no sales tax).

Where all would you suggest to buy some tradesman bessey clamps from or who would have some good black friday deals for clamps in general.

JET had a seasonal sale of their parallel clamps for awhile.  I never bought any because I already had clamps.   I don't know if they're the best ones out there but with the discount people who bought them seemed to think they were a good deal.

If you're looking to clamp up large table tops, you're going to be into huge money for the type you linked to or the many different k-body style others have recommended.  Don't get me wrong, I have many k-body clamps but none longer than 36".  But back when I started out, i bought a handful of pony bar clamps and bought some black pipe to make several long lengths. I still use them to this day.   

Having a large assembly table will help you keep them flat.  Otherwise, there are many jig tables you can cobble together to help you with that.

Looks like Woodcraft has a deal on bora parallel clamps for 99 with 2 x 24" and 2 x 31" what are people thought of the brand. Sale is on until the end of the day

The prices today are $90 for two of the 24 or 31 inch clamps. Acme Tool's usual price on Bessey K-Body clamps is lower. Without no experience with the Bora clamps, I'd lean towards the Besseys.

Speaking of clamps (F style), I found that video a few days ago and thought it might interest some people here. Beware this is an Amana tool sponsored video. The end result is pretty sweet to have multiple clamps using very little spaces in your shop.
