"ΜΛΚ£ SURE YOU USE BOTH EDGES" Says LIMEY . . . The Lime Glass Man
The executives at Doerr Glass Company call economy a double-edged sword for cuttin' costs. They say that true economy is made up of two factors . . . lowest possible price and best possible performance. When you think about it a while, this makes a lot of sense. Y' know, some people insist that if you pay top price, you get top quality. That isn't necessarily true! Neither is it true that if you pay the lowest possible price you get lowest quality. In between, you can usually find the best value . . . the item that gives you the best possible quality at the lowest possible price. A n ' that's true economy . . . Look at heat-resistant, borosilicate laboratory glassware, for instance. Some items made of this kind of glass actually cost as high as 1 0 0 % more than the same item in the Diamond D Blue Line, ff you have to have heat-resistant ware, then you'll have to pay those kind of prices. But if you aren't going to use the item over an open flame, for heaven's sake, think, man! When you begin paying 1 0 0 % more . . . you're wastin' a lot of money. Remember . . . economy's a double-edged sword. Make sure you use both edges!
