people who have worked in manufacturing fields understand how this works- i worked for a lighting company for a number of years- we would have one mold/material to run light fixtures for Macy's and the same mold/material to run the walmart orders---the difference was QUALITY!!!
the Macy's run we were allowed to have 1 bubble in the plastic in a fixture---more than one bubble they were scrapped-
for walmart's order (same part ect) we could have up to 6 bubble in an inch to pass --
it works the same for most things manufactured- different places may buy the same parts- but they have different quality standards---Joannes is about the same as walmart---but they sure like to charge as if they are an lqs---once in a while they even do get something close
when ours built their new store i guess new building meant they could double their prices- i get much better deals at our lqs- for much better quality-
and even if their fabric (feels) the same---look at it- panals are often far from square- or even- designs are---off- lots of lesser standards.
