Note: I just realized that I had failed to update my spreadsheet for the increase in cash pricing, so I was using the new (higher) number of credits required for each size, but the lower cash price. Exactly who is the fool here after all?  My apologies for misleading people. (And for any conspiracy theorists out there, no one from IS contacted me to point out my error; I discovered it myself. Unless they beamed it to my brain, which is a possibility.  )

I've revised the numbers below to what I hope are the correct values. Cash still isn't that bad a deal for E and E+ files of most sizes (especially compared to Main file cash pricing), but nowhere near the crazy deal I thought it was.

Here are the iStock per-credit prices for "smaller" credit bundles:
10 credits - $2 each
30 credits - $1.83 each
60 credits - $1.67 each
150 credits - $1.60 each
360 credits - $1.55 each

But guess what? If you are buying Signature or Signature+ files (I didn't check Vetta), you are  better off paying the cash prices for many of the file sizes, unless you buy much larger credit bundles (even after the recent raise in cash prices, which I hadn't seen mentioned here).

Not so.

Here are the per-credit prices for Sig+ files:
S+: $2.00
M+: $1.83
L+: $1.83
XL+: $1.82
XXL+: $1.84
XXXL+: $1.83

Here are the per-credit prices for Sig files:
XS: $2.00
S: $2.14
M: $2.00
L: $2.00
XL: $1.96
XXL: $1.96
XXXL: $1.97

Here are the per-credit prices for Main files:
XS: $4.00
S: $3.00
M: $4.67
L: $4.75
XL: $4.20
XXL: $4.50
XXXL: $4.43

They think that, and they are right� because it works��

I've modified my original post as it was completely in error.    Sorry!

But it did elicit a good post from gostwyck, so it wasn't completely a wasted effort. 

20% was where it all began. Personally, I'm glad I didn't listen to the voices telling people not to sign up for this industry.

Agreed.  20% was okay when they produced decent volume, and before all the refunds, clawbacks, and general BS came into it.
