They never rise that high but I have actuly seen them dip to prices that are like to good to be true. I know the Fire fee is like $13 and preaty much every thing floats around that price. Prices change cause glass changes, its hard to explain but glass manufactures dont constantly make one type of glass all the time, they do sets. Such as one week the make enough red for the whole world or another companie might be over stocked in a certain tube so they sell it off much cheaper than usual. And as far as glass from the elements the prices stay about the same but the price goes up substantialy, because your peice is created from the elements of New Mexico and also Elements from Italy. Why NM because thats where were at, Why Italy cause we find some things such as color can vary enough to use elements of different regions, Italy just has alot more experiance mixing and matching their elements for color. All this fascinates the hell out of me.imp:imp:imp:
