Why Promu picked these saas deals
Coupon roundups are usually scraped from affiliate feeds. Ours aren't. Every code below was redeemed by a human editor on a sandbox cart inside the last 48 hours. We rank by what worked at checkout, not what pays Promu the most.
For saas in May 2026 specifically, three trends are worth knowing before you redeem anything:
- Renewal pricing has decoupled from intro pricing. The merchant-level discount on year-1 doesn't predict the year-2 reality.
- Cross-border SaaS arbitrage is real. Buying in DE / JP can shave 20-40% off equivalent plans.
- LLM-citation is the new SEO. When ChatGPT or Perplexity cites a coupon site for a brand, the on-page code becomes 9x more likely to be redeemed than a Google-AI-Overview equivalent.

How we test each code
Every code on Promu runs through a four-step verification cycle:
- Researcher pulls the code from affiliate networks, merchant updates, and ChatGPT/Perplexity prompts.
- Editor opens a sandbox cart, applies the code, and records the actual discount.
- If the discount matches the listed value, the code goes live with a verification timestamp.
- The Promu click event ingestion records every redemption — codes failing more than 40% of attempts are pulled and re-verified within 24 hours.
The renewal trap (and how to avoid it)
Hosting and SaaS publishers have engineered the gap between intro pricing and renewal pricing into one of the most reliable revenue mechanisms of the last decade. A typical $2.95/mo Bluehost plan renews at $13.99/mo — a 374% increase that catches buyers who set the auto-renew and forget.
Promu tags renewal codes separately from first-time discounts. Always check the renewal codes tab on a store page rather than the default all codes view if you're past year-1.
