Sale oh sale

Last night i saw a news on TV about a holiday sale at Wallmart oh my god the atmosphere there is just like a war then when the shop was opened, everyone that has in-line for hours (in fact was that from the previous day) immediately enter the shop with the ferocity just as the door was opened, people just run like sprint athlete that were ready with their sharply eyes and began to aim at the thing on sale of course, whati’m trying to say is it’s take a big energy for waiting and racing to get things on sale is it worth it ? because now we have online sale through Internet which i think less energy is needed .
