A Budgetary "What Should I Do" Question

By the way, if you want a sense of your odds of getting extra random URs by buying packets. Assuming they are truly randomly added to packets (since your purchase will almost certainly be consecutive packets)

For 100 packets:
36.6% chance you get no random URs.
37% chance you get one.
18.5% chance you get two.
6.1% chance you get three.
1.5% chance you get four.
Less than 1% chance you get more than four.

So add to option one the fact that you also have a 25% chance that you'll get enough extra random URs that you can try to trade for the two other ones you want (though aren't so critical) but didn't get through your purchase.
