Nope Disney Outlet is off site. Sometimes there is a markdown table but we didn't find anything on site that was less than 20. I thought going during slow season there might be but nope. We did find stuff at the outlet offsite, only I broke down my last day and bought me a 30 dollar t shirt and my mom a 40 dollar long sleeve shirt because we were looking for something in particular and these were the shirts that fit the requirment. Other than those we bought our stuff at the Prime outlet Charecter Warehouse. I think her tshirt there was around 12 and my fleece zip up hoodie was 20.
Unless you budget in a lot for the family souveineers I'd find something else. Pins, Key chains, cups, pens/pencils. We brought back some coasters from the 10 and under store at Downtown Disney (0n site), for some friends and then some other small things like medalions for my nephews and some cute foodie stuff. Much more affordable then trying to get them tshirts.
