[TowerTalk] Copper wire prices

That's exactly what they are now doing with plywood.  Last time I went to 
Lowe's to purchase some 3/8" and 1/2" sheets, the so-called 3/8" was 
actually 11/32" and marked "approximately 3/8".  The "approximately" 1/2" 
plywood was actually 15/32".

Whenever I  start a house restoration or home improvement project, I usually 
buy just the estimated amount of material that I need.  If I take my time 
finishing a project and happen to come up short on somethig like moulding, 
and go to purchase the extra that  I need to finish, almost inevitably in 
the time period between my initial purchase and the second batch, they have 
shaved the dimensions down to something slightly smaller, and it becomes 
difficult, if not impossible, to make pieces from the two batches match up 
perfectly.
