Part of the problem with delivery confirmation is that I would need to send everything Priority mail. Priority plus delivery confirmation costs $5.55 on packages weighing 16oz or less. I ship mainly small amounts of fish foods, such as brine shrimp eggs, flake foods, etc. When you're spending $5 on two ounces of decapsulated brine shrimp eggs, you don't want to pay $5.55 for shipping when you can get it sent for $1.51. So, the only thing I can think of is skipping any guarantees on First Class and only guaranteeing the Priority packages with delivery confirmation. If the P.O. looses one of the confirmation packages, then do I suck it up and loose money on reshipping another pack (I would loose even if they paid the shipping fee again), or do I only guarantee packages that are Priority with delivery confirmation AND insurance?
Delivery confirmation is available with first class (Parcel Post) packages for 75 cents.
