Hi all,

I’m hoping someone else has come across this — I’m seeing repeated £2.50 “Carrier Delivery Label Adjustment” charges from Amazon on shipments sent via EVRi using Buy Shipping, where:

The item is under 1kg

I’ve entered valid dimensions and weight

The carrier-audited values match exactly

I’ve already been charged for the label (typically £3.00)

Example:

For one order, I declared the parcel as 45 × 35 × 16 cm, 1000g.

The actual item was much smaller (522g, 14 × 2.6 × 21 cm), but I over-declared to be safe.

Amazon charged £3.00 for the label — then later hit me with a £2.50 surcharge, citing “Carrier delivery label adjustment due to under-charged delivery label.”

This is now happening across dozens of orders, and after reviewing just a week’s data, I’m already seeing £500+ in unexplained extra charges.

It seems to happen specifically when using EVRi through Buy Shipping, and even when all the entered and audited data match.

Has anyone else experienced this?

I've raised a case with Amazon, but would love to hear from others before escalating.

Any experiences or advice appreciated.

Thanks,
