Dark Patterns

I read an article where it says how online store bribe you to shop and continue shopping. I have been shopping online for a while now it makes it much easier for my parents and I. it pretty easy and sometimes even cheaper than in store. I personally have not had a problem with shopping online but I do always see how they encourage you to buy things by saying its almost out or how if you get this we will give you half off another item. But many times you still pay the same because how much shipping and the tax they charger. There are some privilege of shopping online but then isn't. They just want you to buy more stuff.
