Salamullah,
I believe that it depends on how much you are willing to spend on your Standing Order.
I try to let my affiliates know that they can purchase what's best for them and have given them these options.
You can pick what TCredits you want to purchase.
1 TCredit = 102 VP   cost $1.89
10 TCredits = 1020 VP     cost $18.90
100 TCredits = 1200 VP  cost $29.00
125 TCredits = 1500 VP cost $36.25
Place a Standing Order for a pack of 100 TC - 1200 VP each month. Requires you to earn 300 VP doing the your Daily To-Do list and tabs. 
Personally, I like the S-Builder Co-op Unit on my standing order = 280 VP cost $22.00 
This will give new affiliates every month.  
It's also good to use as a co-op incentive for your affiliates.
You'll only need 20 more VP when you include the S-Builder Co-op Unit with a pack of 100 TC.  
I hope it helps you.  May you go far in your business.
