Pros
If you're able to go FT the pay is great, you don't have to work major holidays, the store closes early and is closed on Sundays, you learn about a lot of crafts and hobbies.
Cons
PT workers don't get very many hours once the holiday season is over and management seems to play favoritism in that manner, seasonal workers aren't included in the holiday bonuses, cashiers have to deal with being micromanaged during every process at the register, especially the return lines ( you literally have to have a CSM by your side from the beginning to the end of every return/exchange and it really slows the process down, not to mention all of the impatient customers just waiting to be helped), you have to enter every item manually, you can't item void and your cancel transactions are monitored (it's almost impossible to ever not do either of the two because customers are always changing their minds or simply don't have enough funds), customers are constantly trying to get additional discounts on top of the everyday low prices and they do, because it's that easy, it is very difficult to go from PT to FT.
