Shopping for home cooked dinner in Shanghai

I clearly have no idea whether I'm an expat or a Chinese. Even my Ayi thought my shopping list was really odd and thought the supermarket was trying to scam me (by a whole £1)! So my first home cooked meal, here is what I bought - in prices converted back to GBP

• £0.68 - Pork Loin x2 Portions (34p each)
• £0.34 - Large portion of chinese vegetables, enough for 2 days
• £0.50 - Garlic, 3 bulbs
• £0.55 - Large ginger
• £1.53 - Bottle of oyster sauch
  
• £2.15 - Bottle of soy sauce
• £0.50 - Bottle of oil
• £0.84 - Two bottles of sports drink (Ayi thought it was expensive water)
• £4.50 - Bottle of Ariel liquid
  

So really, my home cooked dinner tonight cost roughly... 75p!

I couldn't wash my clothes for that price.
