As the title says 10$ store credit, when you like their facebook page.
I think, like COTD, Topbuy also wants to gain access to more users through social networking site.
I could not see any strings or condition attached to this. Please let us all know, if there is any.
I normally dont like their deals due to high shipping cost. So if you like any item from their site, this can be of a little help.
Hope you can get 5 mosquito repellent bracelet from this credit (though I doubt if they really work lol) for 3 dollars.

$80 minimum spend, excludes postage, expiry after 30 days
That looks really bad for the coupon.
I think they will sneak in T&C must spend at certain amount before you can use the coupon.
