Frequently asked questions
Does Grienza sell products directly?
No. Grienza is an independent review site. We do not process orders, payments, or shipments. When you click a product link, you are taken to Amazon to complete your purchase.
How do shipping and delivery work?
Shipping speed, cost, and Prime eligibility are set by Amazon and the seller listing — not by Grienza. Delivery times vary by product, location, and the shipping option you choose at Amazon checkout.
What about returns and refunds?
Returns are handled through Amazon's return policy for the item you bought. Check the product page on Amazon for eligibility, return windows, and refund timing before you order.
Are you part of the Amazon Affiliate Program?
Yes. Grienza is a participant in the Amazon Services LLC Associates Program. We may earn a commission from qualifying purchases made through our links, at no extra cost to you. This does not change our review ratings.
Can I request a product review?
Absolutely. Use the contact form above with the Amazon product link and we will consider it for our testing queue.
