Can u recommend me something like this

It is actually difficult to recommend a specific theme for your needs. Try browsing themeforest.....
Im damn sure that you might need many plugins and this can increase your server load. Better use another ecommerce platform like magneto.

Check out WooCommerce if you have a budget.

go to theme download section

people always say shoppress + wooecommence is the your best choice, of course, no single theme will meet all your need

try wordpress + woocommerce, then search for mayashop or bazar themes in download section.
you can try other themes, but both of mayashop and bazar themes are great.

I think u need Woocommerce with Wishlist member extension, and then for your sales items you could use he coupon system.
I suggest you look at all available woocommerce extensions, i am almost certain you will find what u looking for.
