Some of the other suppliers I use besides those mentioned already are:
https://accusizetools.com/ Their catalog is definitely worth looking at, as they supply some stuff to KBC and BB.
Mapletools.ca (Mississauga on Tomken), They are a VERTEX distributor. Extremely knowledgeable on tooling.
TriHard Tools (Mississauga on Courtney Park), call to see if they have stock, not all listed on the website is available.
Shars.com (USA, price not bad and a better selection of cutting tools than KBC, smaller items they ship, larger you better have a US address you can ship to).
There are a couple of others in Mississauga that are extremely good, I'll have to dig up their names, better selection than KBC or TriHard.
As to increase in pricing, most of the cost is with regards to shipping costs from Asia which depending on when the shipment comes in can greatly affect your price, for instance, I believe BB still has a lot of CX707's in stock (hence the stable price), when the next shipment comes in, we'll see what the new price will be. My sources tell me final shipping costs are always a surprise and are forced to adjust prices when product is finally in hand, shipping companies quote one thing and then up the price (ie gun in hand if you want your product) when it lands. Unfortunately, it all trickles back down to the end customer with the shipping companies laughing at us all.
