Price Protection

Catch silent price hikes before you pay them twice.

Vendors quietly raise prices during auto-renewals. SubDupes compares every receipt with the last one and flags any increase, even a single cent, so you can renegotiate or cancel before the next charge.

The anatomy of a silent price hike.

Vendors don’t usually double their prices overnight. They increase them by 10% every six months until you’re paying double. SubDupes catches the first 10%.

The Compound Effect

Small increases become massive surprises.

A $10/month increase seems harmless. But when applied across 20 different SaaS tools, that “harmless” increase becomes a completely unbudgeted $2,400 per year leak in your finances.

SubDupes shows the annualized cost of every hike it finds.
