Shipping will be combined (despite what ebay's computer says).  1-4 negatives for $1.50, and I'll issue a refund if needed.  Negatives 5-8, 9-12 are 75 cents total for the group of 4.  If you acquire slides at the same time, they are free shipping, so the whole order will be free shipping.

For international buyers, I will add a global stamp for each group of 4 negatives, and add an 85 cent handling fee for the entire order.  I will refund to the point where shipping equals a global stamp for each four plus 85 cents for the order.
