What 51.40 RMB buys in a mini-mart in Tongling Center

I thought I was getting 21 eggs for 8 yuan. I didn't want 21, I only wanted 6, maybe a dozen, but the store clerk I think told me I had to take the lot. It appears that it's 8 yuan per kilo, so the eggs are 20.50 yuan. It's a good thing I like eggs.
I also bought some raw sugar, 2 forks and a "sunning rack". You clip your laundry to the clothes pins and then hang the contraption from a hook that hangs from a rail inside your window cage. I guess if anything falls off, you go downstairs to retrieve it. Good thing I'm only on the 2nd floor.
It cost me a total of 3 yuan for a round trip on the No. 6 bus. It should be 4, but on the outbound I watched other passengers put coins in the exact change box, and I'm sure they only put in 1 coin. I guess the driver didn't care.
As I had to take my tray of 21 eggs back to the apartment, I cut my downtown visit short. I guess it's BYO egg carrier around here, so a miracle I got them all back, unbroken.
I think I'll go back downtown later today and check out a big street market I saw in the side streets near the hotel I stayed in for my first 2 nights in Tongling. I'm guessing that's where I'll find vegetables and fresh meat.
Various bbq duck street hawkers ply my apartment block, but I'm not sure I can trust the cleanliness of hot duck being hauled around on the back of a tricycle in near 90 degree heat. Once I figure out how to ask the guy when he cooked it, and how much per slice or per gram or whatever measure they use here, I will try it. Survival Mandarin 101, and not in my phrase book.
