I know this is a little late, but I was looking for an ebay alternative and was checking out the feedback here on the forum for all the likely choices. I don't know how Poshmark can claim your package is insured beyond what the post office allows. The cost to insure a $5,500 package is unavailable because the PO caps coverage at $5,000. If you were to purchase insurance for $5,000 it would cost a lot. See the following rates from USPS. Also, the USPS caps the amount of insurance that can be purchased for an online shipping label. I think I saw $2500 limit the last time I looked into it, but don't quote me on that number it may be far less.
Domestic Extra Services
Below are highlights of changes implemented in May 2007 to domestic extra services:
Insurance
- All domestic insured items now bear a barcoded label. This includes those items with a value up to $50. Note: Unnumbered indemnity is no longer offered.
- Insured items valued up to $200 use PS Form 3813, Receipt for Domestic Insured Parcel, and receive a scan at delivery, but no signature is collected.
- Insured items valued over $200 use PS Form 3813–P, Insured Mail Receipt, and receive a scan at delivery, and a signature is collected.
- Unlike Certified Mail and Registered Mail scans, an insurance scan by itself will not provide electronic verification that the article was delivered or that a delivery attempt was made.
- Prices for insurance coverage changed as follows:
- Value up to $50 is $1.65.
- $50.01 to $100 is $2.05.
- $100.01 to $200 is $2.45.
- $200.01 to $300 is $4.60.
- The price per additional $100 of insurance, valued over $300 up to $5,000, is $4.60 plus $0.90 per each $100 or fraction thereof.
