Woah, 90 days for free is a great offer. I like their service, but their usual prices are pretty high if you're just getting started with e-commerce and don't really have any budget.
Not sure if I have any idea for a e-commerce right now, but I might check it out. Are you running selling anything on Shopify yourself?
Yeah, I try to stay away from Shopify because of that reason. I can easily use woocommerce for half the price and stay positive with my investment.The only problem with the shopify is that you need to have some sort of initial requirement in terms of funds. Otherwise you are going to drain yourself pretty bad. I know that because one of my friend did the shopify by watching the tutorials. And honestly it didnt worked out because you need to do a lot of advertising in order to move that business ahead.
