Does Alibaba Trade Assurance protect buyers when using freight forwarders on their platform?

I got a few quotes for freight forwarding and theres a sizable range in prices. I just want to go with the cheapest quote, as I don't care if it's an extra 10 days or whatever. I'm wondering...if it's too good to be true and they try to increase the price once they have the goods etc., will Alibaba protect me if I buy through Trade Assurance? Do you recommend that I go with the cheapest option or is that a bad idea?
