I generally like Letsbuy as they have a wide range of products, have bought lots from them but only about 75% of things come on time which is reasonably good. the prices are also quite cheap which does help although there service staff can be rude on occasions.
Would be better if they made there site a bit more appealing and easier to use, and employed people who are a it nicer overall or like there job a bit more but pretty good overall.
I wonder what they will be like moving into the future now that they have joined with flipkart.
