Yes these online stores do tend to re-Stock but you have to be quick, based my experience (with BBTS) since they've got a massive buyer base nowadays their re-stock stuff tend to be limited and are taken up in a snap.
Their postage quote is usually after youve purchased - they will only make mention of what methods they use and are available in their FAQ. Unlike when buying thru ebay that you can pretty much ask the seller fist how much post cost will it be to Australia. Guess coz theyve got an in built computing system on postage to their ordering program which takes care of the post cost computation - but tends to be very pricey and at times overcharged (based on exp with BBTS) compared to what it really should cost....
