Just like sajha's dating site, this one is also doomed to be a big flop.
Am not seeing any reason why anyone should be going through this route when they've access to craigslist, ebay, etsy etc. I don't think I would be able to sell $15 Khukuri for $650 here but I can on ebay or craigslist.

The following statement is common trend to rise influx of visitors. It's free in the beginning and then it's not after it reaches it's marketing goal of desired userbase. Nothing wrong with it. It's how things are run everywhere. But again, on sites like ebay, all fees they're charged are calculated and imposed on sell price that's offered to buyers. How?? well, an item that's being sold on ebay is five fold than seen on alibaba. Of course it's wholesaler and retailer relationship but flaunting 'sajha ecommerce' offering something better, is bit delusional.

Keeping in mind the steep prices charged by other websites to maintain an e-shop, sajha.com has created the resource to allow every sajha member to create and sell from their own online store without having to pay steep maintenance fees.

I think these additions to sajha.com is plausible but from critiques point of view, it's executing plans without proper homework. Lay out some basic foundation of your services' policies, I know it's free doesn't mean one recklessly throw it at users with no regulatory obligations. One can't sell anything on your site, or can he/she? Policy must be written, or terms. Even if it doesn't hold any legal accountability for now, at least new signers will be aware that site is entitled to some policy.

Things like these needs lot of homework which doesn't seem to be the case here.

Best of luck.
