A couple of things to consider... (and i'm open to corrections if necessary) first, someone mentioned price increases due to tariffs. This will affect Chinese products, but many bike products (not all) are made in Taiwan, not China. Taiwan is excluded from the tariffs if what I read recently is true.
Also, although good deals can be found in the fall/winter season, especially with last year's models being cleared out, stock also dwindles considerably. I know some brands have sold out their 2019 stock (first rollout group), which were only recently just announced. So 2018 model options will be slim, unless they are a huge company like Trek, etc. It's all a balancing act.
In the end, never ever pay full price
