How we test Fastmoss codes and prices
A coupon is only useful if it survives checkout. This is the process we run before any code, price, or savings figure appears on this site.

The six steps
- 1Find the code in a primary source
We only publish codes we can trace to Fastmoss itself, an official partner page, or a checkout field that accepts them. Scraped or user-submitted codes are not published until tested.
- 2Record the list price first
Before applying any code, we screenshot the current list price for every Fastmoss tier on both monthly and annual billing so the 'before' number is real.
- 3Apply the code at checkout
We paste FAST50 into the promo code field on the Fastmoss checkout screen and read the recalculated total — we do not trust the marketing claim.
- 4Calculate savings arithmetically
The discounted figures on this site are the checkout totals, with per-month and per-year savings derived from them. Anything we cannot confirm is labelled unconfirmed rather than guessed.
- 5Date and publish
Each page carries the month and the last verification date. If a code fails a re-test, we mark it expired the same day rather than leaving it live.
- 6Re-verify monthly
Every code and price on the site is re-tested at least once a month, and again whenever Fastmoss announces a pricing change.
What we will not do
- Invent codes, or publish a code that failed a checkout test.
- Round savings upward to make a discount look larger.
- Leave an expired code visible to collect clicks.
- Change a rating or recommendation because of commission.

Current status
The FAST50 code passed its most recent checkout test, and the numbers on our pricing page reflect that test.
