Wow, been a long time since I've been on here

I'm a complete Ebay newbie, starting listing my first ever items last night but already I've been badly stung.

I'm selling a couple of DVDs, each one seperately. I was going to ask like £3.50 for the dvd and £1.60 postage to send them recorded delivery (so there's no arguements about proof of delivery) and Ebay has *&%£ed me in 2 ways...

1. The max postage it allows for a boxed DVD ise £1.00, problem is a 100g DVD and case costs about £1.30 to post, why should i lose money on postage because their limits are wrong? They suggest making the postage free and adding the cost to the asking price...makes sense I guess. So I stick the DVD on and put a BUY IT NOW price of £4.99 and with free postage waheyy

and here's the really pissy bit...

2. I didn't know this but once someone has bid...anything, no matter how small, your BUY IT NOW button that you've paid extra for disappears! it only works if there's no bids!

So someone could get my DVD for £0.99 and it'll cost me £1.30 to send it to them! AWESOME!

Is it me being stupid or is Ebay a big old pile of crap?!
