I would bet money that you don't get any bids on that... (and I've been selling my old crap on eBay for 6 years)
Things to keep in mind whenever selling anything.
1) The street value of your items is all that matters.
That's
street value... not retail value. You have to recognize that you're selling two low-end, entry level mics that are not exactly the most popular ones out there. If you were selling Oktava MC012's, it would be a different story, because there is a sizeable market for those... but 219 and 319's... eh.... not so much. Remember to
always do a "Completed Items" search to get a pulse on the market. Before deciding on your "asking price" do a completed items search for the item(s) you're selling. You can find out what price that same item (used or new) has been going for on eBay. This will give you a much better idea of what you can actually expect to get (so that you don't end up over-pricing your auctions or falsely getting your hopes up

). For example, a 319 goes for an average of 75 bucks. A 219 goes for about 55. That's 130. Add in the
street price of a couple cables and shockmounts, and you're not gonna be at $200 (more on that later).
2)
Your shipping costs don't mean jack.
I really doesn't matter how much it costs you to pack and ship it. All the buyer cares about is that he doesn't feel that he's getting "ripped off" on the shipping. Any schmoe can guess the approximate weight of two mics and then figure out how much it would cost to ship. If your shipping comes out to be 3 or 4 times what they think it should be, then you ain't gettin' jack. Fold your shipping costs into the price... cause if you pack and ship using the "official" method, then there's no way you're gonna break even.
3) You will most likely
not break even when selling used gear that you bought new.
...and "making a profit"... LOLOLOLOL...

I almost fell off my chair when I read that. There isn't a chance in hell.

And there are few exceptions to this rule. Unless you have a very hard to find item, or if you got an insanely good deal online (or whatever) where you paid a decent amount less than what every other retail outlet sells it for, then you won't get your money back. And you shouldn't be looking at it that way. The point of used gear is for someone to get something for a pretty darn good amount less than "new" prices (otherwise, they wouldn't be looking at used gear). If people were gonna pay the same (or almost the same) price as "new", then they wouldn't even consider getting it on eBay. They'd go to Banjo Central or MF.com and get the same item for about the same price... and that would include a return policy (in case they change their minds) and a warranty (which is a lot harder to get results from when you buy something used).
4) Don't ever start your auction at the price you expect to get.
If you have a price in mind that you want (the aforementioned "asking price"), then either a) set a reserve price (which has its own downsides) or b) set a "Buy It Now" price. But don't start the auction at that price.
Most auctions on eBay start at stupid low amounts ($1 or whatever) and work their way up based on bids. So if there are 5 other MK319's on eBay, all everyone will see is a bunch of them for 50-75 bucks (that will slowly increase as bids come in) and yours for 200. They probably won't even bother to look at yours seeing how there would be a number of other auctions that are much lower. Sure, by the end of those other auctions they may come up to a price close to yours, but because most of the "major" bidding happens in the last minute of an auction, people will have to watch a few of those "other" auctions end before they would even consider looking at yours. You need to make your auction attractive to people that are just browsing. If you've got the highest price on the block, that a big strike against you right off the bat.
5) Remember that you're selling on eBay.
People buy on eBay for a reason... if they were the dumb schmoes who pay 25 bucks for a cheapy mic cable, then they wouldn't be on eBay... they'd be at Banjo Central payin' 25 bucks for a cheap mic cable.

I bought a 6 pack of mic cables (good ones, too) on eBay just last week for 40 bucks. That included shipping... so you're looking at a street price of aboot 7 bucks (shipped) for a decent mic cable on eBay. Again, it doesn't matter that you paid 20 bucks for it in the store... You're not a store, nor are you
in a store... you're on eBay.
