It is a nice cage & price. It seems to me tho' that the original price was a bit much.
You do have to watch getting things from craigslist. Sometimes the folks on there are not always truthful. I have never bought from the site, but do know of a few bad deals I have heard of.
It is good to have everything all set & ready for when you get your macaw, but I do agree you may be jumping the gun a bit too soon on this one.
I'm not trying to dissuade you on getting a cage or a macaw in your future, but you do need a good job & a bit more money than the cost of a cage to properly take care of a macaw. Their food alone can be costly!
And of course they are not the cheapest parrot to buy either. :twirl:
Anyway, just think on it awhile before deciding & when you are ready I hope you Mom lets you have one.
