Market forces and maybe the consequence of one of the most discussed WGs (Bora) in recent memory. I mean 18,000+ posts for Korean WGs... really

So don't complain guys now that she wants £320 for a basic rug'n'tug and CIM, DT etc will dig deeper holes into your wallet

You have brought this on yourselves. You have made it plain you loose all sense of reasoning as soon as you see a genuine Korean pop up. So don't blame her or her pimp for rinsing you dry.
I once posted a remark saying price rises have got nothing to do with UKP. Based on this evidence I humbly take that back. Bora and her teammates are no doubt reading these threads or are aware of the clamour from punters to get in Korean's knickers.
The title of the thread captures the clamour quite succirnctly.
Happy punting (Koreans) chaps!
