For those who have been here, I just have a few questions I would apapreciate your help on. Thanks in advance:)!!!

1) As far as cellphones go  is it better to get one of those prepaid/pay as you go phones or should I get a plan? Why or why not? Should I got to Yongsan to get a phone?
-My friend said I could go into any of the LG Oz stores and get one...so if someone can confirm or deny that let me know.

2) Everyone says to go to Itaweon to find clothes and shoes in my size. Are there specific stores/areas I should check out? Are there any other places in Seoul I should look into?
-I really want to get some sneakers (preferably Puma) and some warm boots!

3) I would like to get a futon or small couch in my apartment...what's the best way to look/find one? Where's the best place to get one for a decent price?
-It doesn't have to be anything special, just comfy, clean, and not too expensive.

4) What are some good sites to find material for afterschool classes with 1st, 2nd, and 3rd graders?
5) Someone said there is a store where you can get glasses for 20,000 won. Does anyone know the name and location of the store?

Those are all the questions I have:)...thanks for your advice!!!
Be blessed
