Personally I don't think I would. I like to hold the bow in my hand and shoot it to see how it feels.
I think if you could go to a shop to try the bow out first or at least look at it and hold then go online to save some money is fine to do. I bought my bow off ebay and saved about 40$. But if you don't look at it first and then decide you don't like it after you get it then your probably stuck.
