Do they have Savers and Trimmers?

Not sure, but I bought my Wahl clippers and small beard trimmers from the store.. So they do have some at the store.. And usually it will read on-line only if not at the store

Shavers and Trimmers: Yes, however it's sometimes hit or miss with which location has the premium units. It would be logistically impossible for any single store location to carry all that the website may offer. Moreover, it's normally a best practice to research online, get the product information (including the UPC code and SKU number), then call the store to validate availability. Sometimes the best way to get exactly what you're looking for is to bring that printout of the product page, in case it's not in stock. This allows the store personnel access to what they need to place the order if it cannot be located elsewhere in thier system. Failing all that, GOOGLE the UPC of what you want and select NEARBY, then sort by price. This wasn't meant to be long, or come across as "pedantic ". My desire was to fully answer your question and give other options.

They do but sometimes they dont have a wide variety in store

But do all Kohl's store actually have everything showed on their website
