I think one of the most obvious trends that will continue to get bigger in 2015 is mobile commerce. I specifically mean shoppers buying things on mobile devices (smart phones, tablets, etc.).

I also see a need for the majority of retailers to create a better shopping experience across devices. Having a "mobile specific" version if your store isn't going to cut it. Usually a mobile specific site omits some functionality or some products or perhaps both. Neither is a good idea for keep customers engaged.

Retailers should consider using Responsive or Adaptive website frameworks such as Zurb Foundation or Twitter Bootstrap. You can create one experience that adapts to each device while not eliminating functionality. This should be at the top of the list for enhancements that will delight customers.

I would also say that looking back and going forward, stores with a specific target or niche seem to perform better than a store trying to please everyone. Don't let the numbers fool you, a larger customer base doesn't mean more money if they don't fit your product or market. Look for ways to grow within your existing demographic.

Longer term I think the following things should be kept on the radar for the end of 2015/2016:

• sales through social media
• online fitting rooms with augmented reality
• clothing custom made for individuals from 3D body scans
