Does saving a product to a wish list reserve it?

Check that the saved product still has your preferred option. Consider whether the saved entry belongs to the same seller.

How can I check whether a seller-provided guarantee applies to the purchase?

Look for exclusions that limit the advertised scope. Ask for clarification when the listing and written terms seem inconsistent.

How can I decide whether this product meets my needs?

A popular option may still be unsuitable for your particular priorities. Look at the complete description rather than only the most prominent marketing message.
