We just got our Grade Three Science Kit which retails at $73.00.
I checked the www.enasco. com site and came up with a price of about $55.00 for the contents. The kit comes in a 31qt rubbermaid box which is about $12.00. So the total is about $67.14.
The differance is about $6 which we would likely spend in gas getting to the stores!
This is the balance that is included in the kit http://www.enasco.com/product/SB28259M It is plastic and does not look that sturdy especially if being used by boys!
