Oh ok. ThankyouI don't know if that place is good. Do they have good feedback? Best way to figure out if they're good is to see if they have a lot of good reviews from people who've bought corals from them.
I bought mine at my LFS. You should buy yours at some place that has a decent price (wouldn't go much over $30 for a small frag, I think), and has good reviews. Or on here, if you can find someone selling it.
"Bump" is what you put in a thread to move the thread up. A thread that has just had a post added to it goes to the top of the forum section it's in. Intentionally moving a thread to the top of a section by making a post that has no other purpose than to move the thread to the top, is called bumping. It should pretty much always be reserved just for sales threads (but only as commonly as is allowed in that area), or for threads with unanswered questions, in hopes of getting more replies.
