Buying data online shouldn’t feel like stepping into a minefield. But for many businesses, that’s exactly what it is — endless PDFs, vague consent claims, dodgy brokers, and “GDPR compliant” labels that crumble under scrutiny.

That’s why The Data Supermarket was built: to give buyers a safe, fast, and compliant way to purchase data without the guesswork.

Here’s how you can buy data safely — and how TDS makes it possible.

Always Start with Real Due Diligence

Most platforms leave you to do your own due diligence. That means hours (or days) vetting the seller’s source, consent model, privacy policy, and risk exposure. At TDS, every listing has a full Due Diligence Profile — instantly viewable before you buy. This includes:

  • Privacy policy evidence 
  • Data sourcing method (B2B or B2C, direct or aggregated) 
  • DPIA, collection method, and lawful basis 
  • Seller’s consent mechanism 
  • Any third-party sharing rights

Plus a hell of alot more, somply click DD Details on any listing for the full compliance summary and paper trail. No delays. No surprises. Just full transparency before you click buy.

Check the DD Code — It’s Your Proof Trail

Every time you download data from TDS, a DD Code is generated. It’s a unique identifier that ties the data to its source, upload date, and compliance profile. 

This replaces the traditional two-week audit process most companies run before onboarding a new supplier. 

Need to respond to a DSAR or regulatory check? Your DD Code + email or phone number gives you full traceability in seconds.

Use Suppression Matching to Stay Clean

Uploading a suppression file shouldn’t be optional. TDS lets you instantly match any product to your suppression list with one click. 

You can:

  • Suppress against all previous purchases automatically 
  • Upload suppression files for your entire business 
  • Use the DupeCheck tool for instant feedback (under 3 seconds)
You’ll never pay for duplicates. And you’ll never call the same person twice.

Don’t Guess What You’re Getting — Filter First

Buying blindly is risky. That’s why TDS lets you filter every data product before buying: 

Use Advanced Search with live filters across any field the data includes:

  • Use commands like: equals, not equal, like, exclude, more than, less than, between 
  • Example: Only want records where “age” is more than 55 and exclude Gmail addresses? Done.
Get live counts and apply instantly — no need to request samples or email the seller.

Trust a Platform That Backs Buyers

TDS isn’t just a marketplace — it governs the entire payment and dispute system.

  • Every transaction includes a 7-day dispute window 
  • Seller payout is held until the buyer's 7-day dispute window has closed
  • TDS investigates disputes directly and issues refunds where necessary 
  • PayPal Pay in 3 and PayPal Credit options give buyers flexibility
And all of this sits on top of a secure global PayPal partnership — so your money is protected by both TDS and PayPal.

Get Forecasts Before the Data Exists

For lead buyers, TDS offers a 7-day availability forecast based on historical uploads and real-time live delivery checks. 

Planning a campaign and need 3,000 leads next Thursday? See which seller has volume forecasted — and line up a second provider instantly if needed. 

No surprises. No dry pipelines. No overbuying.

What It Means for You

Safe data buying isn’t just about avoiding risk — it’s about getting real confidence and operational speed. 

TDS replaces weeks of manual checks, phone calls, and guesswork with instant transparency, smart tools, and full protection. 

If you're still buying data the old way, it's not just slower — it's riskier.
