Anyway, I carried it to the bank (은행) next door today, which in a happy coincidence has one of those coin sorting machines in the lobby--not all banks do, at least not for public use. And in fact, I wasn't allowed to use it; the bank guard did the honors, and not because I am a foreigner deemed incapable of such a complicated procedure, but because it actually was a complicated procedure.
About ten minutes later, he gave me a box full of rolled coins, which I then took to the teller and converted into folding money. My take: W160,310.
Not a huge amount, but particularly welcome at this juncture, as I am, in a word, skint: first, there was my trip to Japan; then I had to buy tickets to Atlanta for August (Leaving on August 9, returning August 19). The last straw, my computer died two weeks ago--I can't complain, except for the timing: I paid $650 for it, a Toshiba Satellite with a big, big screen, almost four years ago.
So I really had no choice but go over to Yongsan Technomart and buy a new computer, opting this time for a desktop model. I paid as little as I could get by with, and came home with a 20 inch LCD screen for W129,000 and a basic box for 300,00. For the geek contingent: 2GB RAM, Intel Celeron G530 @ 2.40 GHz, 64-bit, 250 GB HDD, Multi-DVD, running Windows 7 Ultimate (English). No webcam yet, so no Skype.
