i just dont get it, why ordering very cheap and very expensive package

okay, so today i click on some buy sell service to see if someone is ordering some afordable packages for xrumer blast and scrapebox blast, and i saw services were ultra expensive compared to last my buys

but i was suprises to see some long time member wrote "i just ordered it"
and i recall this same person writes things on many posts, on many xrumer and sc blast services

so i dont get it, why did he buy 20k blast from person a at for example 40$ and then from someone else (later) at 85k$
i dont get it....perhaps it was just doing favors to all friends and bumbing threads to newbies?

Maybe they have different urls? differnet AA lists.

And better quality maybe?

hehe lukab, you woudlnt believe on who i was reffering too ))
anyway i thought all AA lists in circulation are more or less the same, i though the max awaible (scrapebox) AA list in uniq domain count must be lower then 12k

but thanks for answers
any idea how many AA uniq domains are ?
