PSA: Indie Gala Interstellar Bundle Happy Hour is on!

Second bundle. If you're a early buyer, get 3 bundles.

If you BTA during the 1st week, you'd receive 1+3 gifts
If you BTA after the 1st week, you'd receive 1+2 gifts
If you didn't BTA, you'd get 1+1 gifts

You must select "Yes. Buy as a gift" or you will not receive the extras.

So in your case, if you paid $6.89 and purchased as a gift, you'd actually receive 2 bundles.

If someone were to BTA during the first week for $4, then do the "Donate 5 gifts paying more than: $32.73" they'd receive 20 bundles for $36.73 which comes out to $1.84 per bundle.
