Thank you for taking your time to review this. here is a list of all the transactions that you might be looking for.
First of all I wanna mention I have 2 real life friends xkepa and boomshalal.we have been very close since we began the adventure in nostalrius. I believe we all added each other to the friend list at the lowest possible level(at least I did this to them) and now we all hit 60. those are the transactions I had with them.I gave them some gold to buy lvl 40 mount(i was around lvl 35). 50 gold to xkepa for 16 slot bags. he=lvl43 me=lvl40.580 gold to xkepa in 3times for his epic mount.( I wasn't even 60 atm) first time=400g second time=150g third time =30g.I also want to mention that after I hit 60, he gave me 2 black lotus.(Worth 170g) to help me buy mount too:D
Normally I make money from herbing, disenchanting and selling random drops into ah. Recently I sold a recipe( mob dropped) for 200g in ah.sold 4 black lotus(gathered 2 on myself and got 2 from xpeka that I just mentioned above)-: was sold through the trade window for 330g in total.sold 20 essence of air for roughly 200g in ah. Sold a rare quality mace(got it from the bags in silithus) 150g.And I bought a lot of high lvl green or blue gear from for disenchanting purpose.
Those are all the recent transactions I can recall. They are guaranteed to be true since you can easily figure this out by looking up to the data. If there is something missing, plz let me know the circumstances so I can explain to you. Sincerely
