Going to stores and ask for particular books is a waste of time nowadays. Since most people order books online they don't keep a large selection in the stores any longer. The other day, when I ordered two packages of books made of papers in a famous online store, I realized that the delivery of the books was completely different. The large package was quickly delivered to a tobacco, and I received an SMS when I could fetch it. The smaller package was sent by snailmail and I first received an SMS when the post received the package. It took five more days before I received another SMS telling me that the package had arrived. I guess the postman had to bring it out to my door and to find out that the package was too large to get through my door. I rather get my stuff quickly delivered somewhere I can fetch it.
I also needed to upgrade some of my whitegoods for the kitchen. After looking around I knew what functionality I wanted and also what particular brands I preferred. Asking for those items in the stores gave me funny answers. Two different chains they told me one item wasn't possible to buy in that particular combination of brand and features, and the other item would be terrible expensive and not as good as the stuff they had in the store.
The truth was that the first item was possible to buy online and it was even a sales success in an online store. The other item I found in one of the chains online store, and it turned out not to be at all that expensive (30% of the price they told me) and to have better technical features than the stuff they tried to sell me in both stores.
The conclusion is that it is safer to buy things online, where you can compare functionality, prices and availability than in old fashioned stores where sales people just try to sell whatever they have. I feel sorry for the old people who still go to stores and for the innocent consumers who trust sales people to tell the truth.
