I've used sheinside several times and have had no issues whatsoever. I bought three t-shirts and a top and the ordering process was easy and quick. Delivery was on time and the items were of good quality and very original designs. I would have no hesitation in shopping there again.
Amazon are good in the main. My only issue is that when goods are despatched, quite often you only get an email the night before. Sometimes you just can't arrange to be in at such short notice and then you have to re-book the delivery... goods are usually good value and it is one of the first places I check for comparisons...
I've used booking.com for at least two years, and I always check out their deals first. The reserve now, pay later deal is great, and the choice is very good, allowing you to widen the search area with ease.
Our dogs love the tripe from here - can't find anything that offers the same value. The loyalty scheme is good as the redemption options are tailored to your needs. Quick delivery and very quick customer service.
