I have right now ( and nearly always have similar quantity on hand) about $20,000 of mint with gum Australian and Australian Antarctic Territory and Cocos Island and Christmas Island decimal currency period stamps, to sell well under face value for postage. 

All are valid for use on local or overseas mail - letters and parcels of course.  AND you can pay the Registered fee on domestic mail using mint stamps as well.  Depending on the quantity you order, you will save a TON on your postage costs. 

You save a cool $225.   No GST is added to your invoice either.  I can tailor a package to suit your needs.  CATALOGUE value will be many times face value most times.   Generally these are in full sets .... I can often supply the entire order in the attractive Post Office Presentation Packs - where the stamps are fresh, clean, mint unhinged, and all in complete sets.  

 Absolutely perfect for anyone sending out philatelic mail to clients .. either here or overseas.  OR also perfect for folks overseas placing mint Australia up for sale on eBay etc.  Much of what I sell you retails for WAY above face value.

 Remember, these Post Office packs cost 45c MORE than face value to buy from the Post Office.  Buy $500 face value off me for $400 and you are likely getting something that cost the original buyer $600 from Australia Post.  In that case you are paying me 50% less than original cost!

 A heavy parcel Sydney to Perth often costs $50.  An air parcel to USA or Europe often costs $150 these days.  If you use my stamps to mail these parcels, you simply charge your client the face value of franking used, and pocket $34 as your EXTRA PROFIT by buying it under face.

 Or, if you run a small business or want to impress the boss with your business savvy - save your company $100's today!

 Full commemorative sets or mini sheets lightly cancelled are generally worth far MORE than face value when lightly used, so using these on mail is a VERY much appreciated gesture by those receiving them.  Indeed, the Stanley Gibbons catalogue often prices FINE USED stamps from this era at MANY times their face value.  

 Many dealers mail heavy parcels overseas, have them lightly cancelled, and ask the sender to mail the used stamps back, which are still worth at retail, as much or MORE used as they paid me for them!  Permanent "FREE POSTAGE" for you if you are organised enough to do this.  Do NOT pay full face to the PO, when you can save $100's and buy off me! 

 I am Sydney's best known and most aggressive STAMP BUYER.   My Yellow Pages ads, stamp magazine ads, internet ads, and 25 years of strong word of mouth ensures I get a CONSTANT stream of this material coming to me for purchase.  I often buy collections containing runs of mint blocks of 44 spanning 20 or 30 years.  Face value of these is often well over $1,000.  I simply add a small mark-up to my buy price, and sell it to you.  You save $100s buying this off me and using it on your mail, and selling off or keeping the better items, and using up the rest.

 This is important.  NOTHING is cherry picked or removed by me.  I do not stock or sell single modern sets and therefore do NOT take out the good thematic items as some/many other dealers do when THEY sell postage.  When you buy from me you do NOT get useless and ugly philatelic "dregs".  You get the LOT - as it comes.

 I can sometimes offer stamps in full MUH sheets that some investor bought decades back.  22¢, 24¢ and 27¢ were commonly bought in sheets by investors as they were letter rate values at the time.  Remember Australia has not made legal tender circulating 1¢ or 2¢ coins since 1991.  Australia Post has not issued any stamps below 5¢ since 1988. 

 All transactions in Australian retail commerce are "rounded up".  I am advised that a 22¢ and a 27¢ stamp (49¢) on an envelope are acceptable to pay 50¢ postage.  Ditto a pair of 24¢ values - 48¢.  Your PO cannot sell you a 1¢ or 2¢ stamp, so surely can hardly expect you to add one to a letter franked with 48¢!  And even if they did you have no 1¢ or 2¢ coins to pay them, nor them to give you as change from a silver coin.
