First, dont hold me responsible for what happens after I do this LOL
It varies. Some will. The only thing to do is sit and wait. It could happen either right away or sometime in January to promote sales when people are feeling very "shopped out". Gen suppliers often want to make space for new product coming out...and they will heavily discount product that was slow for them...doesnt mean it is bad product. Never know when that will happen but I have seen it Jan-March as they clear the decks for what will debut with CHA2017 (the big industry convention) in January.
You might want to keep an eye on sites that
always discount like Oozak and carries a lot of companies. Really nice guy and they just launched Craftzak and there could be even more on that site-which will be massive with all kinds of crafts. Another one is Susana's Custom Art and Design-very nice lady.

More would be Scrap Mart for dies. Just Rite often has Spellbinder dies on sale, etc. 123 Stitch runs weekly sales all the time and often have some small discount on many companies. SOMETIMES Amazon might have a good deal or might be the only one to have older stuff anymore...or may have international companies. I tend to go to them more for supplies like CS.
You might also want to take a look at Gina Marie dies. Always a very good price and can be very similar to other product.

Beware Joann's. They seem to mark up higher than mfgs so that 40% off isnt really as good as it sounds.
While I like SSS's own stuff...I usually dont buy other companies' stuff from them b/c the prices (to me) are high and the sales are often not so great (like 15%) However...you cant get their stuff anywhere else. So I wait for 20% sales and try to cherry pick what I really really want. The exception there would be the time limited stuff.
Keep an eye here in our selling thread. People are always clearing stashes and while there is always a lot of SU, there can be ANY company showing up.
Bottom line...like everything else...one has to do their homework.
Also...my personal advice is to let things live on your wishlist for awhile. It is very common to either decide later you dont actually like it THAT much....or to see another one from another company you like even better. Six months is a good time frame imo.
