So how old can they be? I think its the last numbers in the LOT# that tell the date in which they were manufactured? Can anyone back that up? How old can they be....i think mine are a year old! Can i dispose of it in the garbage...?

That would be me.
The lot number on the packages is the manufacture da te. The four numbers stand for the month and year the product was made. For example, 0411 would mean the test solution was manufactured April, 2011.
Now, as a rule of thumb I replace my kits each year along with many hobbyists. I feel that this is the best way to ensure the accuracy of the kits.

Yup, being open. I would not use any API test kit that was manufactured more than 3 years ago.
