Affiliate links are special tracking links to a retailer's website, like Amazon. If you buy something after clicking one, we may earn a small commission at no extra cost to you.

Yes, mainly on our Study Essentials page, where we recommend books, calculators, and stationery through Amazon affiliate links.

Affiliate commissions help cover website costs and let us keep all study notes, PYQs, and mind maps completely free for students.

No. The price you pay is exactly the same as buying directly from Amazon; the commission is paid by Amazon, not added to your bill.

When you click an affiliate link and complete a qualifying purchase within Amazon's tracking window, we earn a small percentage of that sale as commission.

Using our links costs you nothing extra and helps support free study resources for other students, but it's entirely optional.

Yes. They simply redirect you to the official Amazon website; we never ask for payment details or personal information ourselves.

We do not collect any personal or payment information through affiliate links. Any data collected during checkout is handled by Amazon under its own privacy policy.

No. You'll shop on Amazon exactly as you normally would - same prices, same checkout, same delivery and returns process.

Not every product is personally tested by us; recommendations are based on relevance to students, ratings, and reviews available on Amazon.

Yes, our Study Essentials page focuses only on books, stationery, calculators, and other learning tools relevant to students.

No, clicking a link never costs you anything. You only pay if you choose to purchase a product, and at the normal Amazon price.

Affiliate tracking links themselves don't expire, but individual product listings on Amazon can go out of stock or be discontinued by the seller.

Prices on Amazon change frequently due to seller decisions, demand, and offers. We don't control or set these prices.

Sellers sometimes run out of stock or discontinue listings. If this happens, we try to update the page with alternatives when possible.

Ratings and reviews shown for products come directly from Amazon, based on real customer feedback, not from us.

Returns, replacements, and refunds are handled entirely by Amazon according to their return policy, not by Blink Study Notes.

Amazon (or the respective seller) handles all customer support, order issues, and after-sales queries for products bought through our links.

No. We recommend products based on usefulness for students first; commission is simply a byproduct of that recommendation, not the reason for it.

Currently we do not receive free products from brands. Our recommendations are based on genuine research and student needs.

Because affiliate links are designed to take you to the retailer's (Amazon's) website, where the actual purchase happens.

You can, but affiliate tracking is time-limited, so it's better to click fresh from our Study Essentials page each time you plan to shop.

We review and update the Study Essentials list periodically to remove unavailable items and add newer, useful products.

Yes - simply sharing our notes with classmates or visiting the site regularly helps us grow, no purchase required.

Any warranty is provided by the manufacturer or seller as per Amazon's standard policy, not by Blink Study Notes.
