I wouldn't feel comfortable if I were looking to make a large ($-wise) purchase & a salesperson were saying *hurry up! buy now! prices are going up!* You shouldn't feel pushed.
But, to answer your question, you can check out this link:
I don't think the prices will increase on "Monday" tho.
Have you checked out any of the pricescope vendors/done a pricescope search for what you're looking for? I can almost assure you that they won't make you feel pressured.
The price increase thing is a catch 22 for a retailer because a client can take it the wrong way as being a pressure tactic. Therefore, I don't mention this possibility unless asked, but prices can/do increase without much notice...so you take your chances.
It is true that prices are/have increased for the 2nd time this year, but it is a variable if or when you see the increases at the retail level with different vendors.
