Looking for theme e-commerce store

recently installed a plugin price comparison into my werdpress website,
looking for a wordpress responsive theme,
anyone can help or advise about this please?

What is the topic of your web site?
So we can try help you find what you need

it’s an e-commerce store
the plugin works with wordpress,
after get it installed, then insert keys from amazon, ebay, aliexpress, etc…
then will be able to import products / items listed there into your store, which will allow visitors to compare prices and select which better prices they can select,
hope this made it clear,

Any template that you like can be used then with no problem.
