I recently bought some physical silver localy, during the spot price dip on the last few days of the year. The larger your piece of silver the closer you can get to spot price... 1000oz bars should be nearly at spot price but who's trading in $30k blocks of silver?
I got a 100oz bar for aprox $1.50 above spot, and some silver Maples for about $3 above spot (bought a low volume). I could have bought it all in maples but wasnt interested in the "coin" more the comodity. Being local I was able to get it right away and the only thing resembling shipping was a drive across town. That same timeframe an order from Kitco or Apmex would have been 5% more plus shipping.
If you're going to compare Coinabul to any of those services you might as well skip it and use the other services...... as soon as they accept BTC. Different people got their BTC in different ways, over the past year you could have BTC at a cost of anywhere between $2 and $30, so your purchase is the realization of any profit/loss in your BTC as well. You just cant do that with buying it in dollars elswehere, the swing in the silver price is only around $25-$50 since the run up over a year ago.
So far Coinabul has been very quick in answering any questions I've had through his contact on the web page, I'm just hoping he's on a week off cuz I've not heard from him for 5days after plaing an order and asking a question again.... we'll see.
