Favorite E-Commerce websites?

Amazon - easy to search, prioritize results and get reviews, prime delivery...and they have everything. 

Zara, Amazon; Shakti's website is actually really good bc the pictures are large and you can easily see the colors. I find images with actual people to be very realistic and those that just show the product to be more "sketchy" or unreliable bc you can't see how it looks. Navigation and searchability (a word?) are also key. 

I'd say Pampered Teacher, but we're going through our own redesign... I'd be happy to discuss with you if you'd like.

I'm a fan of Casper Mattress' ecommerce website. Tells a story but also really easy to buy from. 

Kind of along the lines of Sogyel's comment -- I'd look at some of the "digital first" or "direct to consumer" brands that have popped up in the last few years. For example: Casper, Bombas, Everlane, Warby Parker, Allbirds, etc. Away (awaytravel.com) might be especially interesting to you, given your travel focus.
