Hi, You have great shop. You can start from make a review about your site from another blogs/sites. Put anchor text such as "Electronic Shop", "Video Games" and link to your homepage or your categories. You can put refferal program for your shop to get customer and make sharing commission if anyone order from refferal. Thats good enough to get traffic. Text Link refferal is good for SERP and banner refferal is good for traffic.
So far so good, why do you need a review? The only think I can say is your dynamic URLs you may use to redirect it to more meaningful URLs with keywords and get links for both your inner pages and home page. Also add a self anchored link at your footer. That's about it I guess
