Affiliate Disclosure

Last updated: July 11, 2026

MarketCrystal participates in affiliate programs, including the eBay Partner Network, Impact, CJ Affiliate, Amazon Associates, and individual retailer programs. When you click a "Buy" link on one of our commodity boards and make a purchase, we may earn a commission — at no additional cost to you. The price you pay is the same whether or not you use our link.

Affiliate relationships do not influence our rankings

Rankings are sorted purely by price-per-unit from live data. Every board — dollars per terabyte, per gigabyte of VRAM, per watt, per watt-hour, per gallon — is ordered by the same objective math applied to prices we fetch from retailers. We do not take payment for placement, we do not reorder results to favor a paying partner, and a retailer paying us a higher commission never moves its listing up the list. The cheapest option on a real per-unit basis is always at the top, whether or not we have an affiliate relationship with that seller.

Prices and availability can change

Prices, stock, and availability shown on MarketCrystal are fetched from retailers and can change at any time between our data refresh and your visit. Always confirm the current price, condition, and availability on the retailer's own site before buying. We do not mark up prices, hold inventory, or process any transaction — you buy directly from the seller.

Not financial advice

Consistent with our Disclaimer, nothing on MarketCrystal constitutes financial, investment, or purchasing advice. Our boards are informational tools to help you compare cost per unit; the decision to buy any product, and any resulting outcome, is solely yours. We make no warranty as to the accuracy, completeness, or timeliness of any listing.

Why we tell you this

Affiliate commissions help fund the data pipelines that keep these boards live and free to use. We disclose them plainly because trust in the rankings is the entire point of MarketCrystal — the numbers are only useful if you know they are not for sale. If you ever see a ranking that looks like it favors a paying partner over the cheaper option, it is a bug, not a business model. Tell us.

This model is deliberate: a referral fee only reaches us when you find a better deal and take it, so our incentive and yours point the same way — we earn nothing by steering you toward a costlier option. That alignment is the whole reason we can keep the rankings honest and the site free. For the full argument, see why we're free.
