The sad thing is no post offices ever answer their phones and would claim they don’t know anything about this. So calling them won’t get us anywhere. If I’m not refunded for these scam charges I will be leaving shopify. It’s shopify’s responsibility to ensure we aren’t scammed like this on their platform when buying shipping through them.
Topic summary
On July 4th around 7:30 PM, numerous Shopify merchants experienced a massive wave of fraudulent USPS shipping label adjustments, with charges ranging from hundreds to thousands of dollars. One seller reported over 30 adjustments totaling $700, while another was hit with approximately $5,000 in unexpected charges.
The Issue:
- Adjustments cited incorrect weight/dimensions, but merchants had intentionally rounded up weights to avoid such charges
- Many packages showed impossible weights (0.16 oz—less than an empty box)
- Charges of $22+ appeared on First Class packages where dimensional weight doesn’t apply
- Dimension discrepancies were fractions of an inch that wouldn’t affect pricing
Merchant Frustrations:
- Initial support responses were unhelpful, directing sellers to contact USPS or file claims themselves
- Shopify holds the merchant shipping account, making independent dispute filing ineffective
- Charges processed during regular billing cycles despite the acknowledged error
- Some merchants incurred overdraft fees and had to postpone sales/shipments
- Support estimated 12k-50k adjustments were impacted (potentially $1.1M+ in erroneous charges)
Resolution:
- Shopify eventually confirmed a USPS billing system error affecting July 4-5 shipments
- Refunds/credits were promised and began rolling out
- Merchants expressed anger over lack of transparency, delayed communication, and inadequate compensation for secondary damages (overdraft fees, lost sales)
- No claims filing with USPS required for affected merchants
