If you take two extremes of retail shopping, there’s WalMart (broad selection, low prices, relatively few outlets) and there’s 7-11 (narrow selection, relatively high prices, lots of corner outlets). With 7-11, you presumably pay a little more for a little more convenience.
To the organic chemist, Aldrich is convenient (free shipping!), it’s typically high cost and the quality ranges for completely satisfactory to below average. The convenience and the high cost = 7-11; the extraordinarily broad selection of compounds, a little more WalMart-like. My experience with the customer service has been pretty good, actually.
So what is Aldrich? I think it’s more like a department store than anything (you can buy Aldrich brand glassware, not that I know a lot of people who do.) What do you all think? Do you have any favorite suppliers? (Seeing as how Acros is an advertiser, I have nothing but good to say about them.) What store do you equate with your favorite supplier?
