I would like to tell you about advantages and disadvantages of e-commerce. 

It's good that e-shops have products with lower price. It's good because you can buy products without any live-communication with other people. It's easy to compare because (Повторяешь "because", если сам(а) писал(а) лучше используй "since") all (the) products that you see is (are) here and you have integrated tools for this comparing. There are a lot of bonuses here because e-commerce is profitable for sellers. And it's good because stores are open all the time. 

And disadvantages (На русском имеет смысл писать "И недостатки" но на английском они так не пишут, лучше "E-commerce also contains few disadvantages) . First of all, E-commerce have (has) security issues and it's a really big problem because you have to share all (of your) contact information with websites. Second is the inability of (to) experience the product before purchase, in case for (of) clothes. It's hard to buy clothes without experience (experiencing) the product. And It's bad because you have to wait your shipment really (for a really) long time.
