Can i get men turtleneck sweaters below $20 here?

YES

I've seen turtlenecks there, as far as price, you'll probably get them below $20 when the season is ending, on clearance rack. Good luck!

Possible, this not the season for them

Possibly

Sure. There is a variety. I have seen turtlenecks for 20 dollars at this location

The assortment here is iffy. Many shoppers have scored deals at this store but i didn't get great deals. You may be lucky MillyTheToddler. Just check the store. Goodluck
