I'm sure this violates every community value on VMK, but wouldn't it be fun to pick out one of those little beggars in the Emporium and tell them, "Yes, I will buy you a bat magic. I will buy it today and I will give it to you next Friday. In the meantime, you have to do everything I tell you to do. If you fail to do so at anytime, I will not give you the pin."
Then just start working them like a mule you don't have to operate yourself.
"OK, today I want you to Ned all day. You can only play the Jungle Cruise and at the end of the day I want you to purchase three tiki fountains and give them to me." (that would be 120 games of Jungle Cruise for you keeping track at home)
"Go win 64 blocks of ice and give them to me."
"Play whatever games you like and earn enough credit to buy me an explorer outfit"
If you played this right - and the person actually did it all - you could probably get more than 10,000 credits worth of stuff - and teach the beggars how to actually earn credit themselves next time.
