It has both<em> an advantage </em>and<em> a disadvantage</em> on the consumer's end. As an advantage, it helps consumers find the perfect product or service that they have been looking for online. It helps people with their browsing experience and guides them in being directed to the product or service that they want thus,<u> saving more time.</u>
On the contrary, <em>it can also be a disadvantage on the consumer's end.</em> Since information from the browsing history has been saved,<u> it can be troublesome for the consumer if she wants to control her spending.</u> It can be tempting to buy the products or services which she doesn't really need because it keeps on reminding her while she's browsing.
This could be because they understand their frustrations, or it could be you have not been loyal to them thats why they treat you this way.
