about_thrifle
ChatGPTWhat Thrifle is, what each database covers and how big it is, how to cite it, and which tool answers which kind of question.
Finance
Overview
Ask about any US retailer's return policy: the return window, whether returns are free, restocking fees, holiday extensions, and a grade from A+ to D-. Check whether a store price-matches, what military and student discounts it offers, what a brand gives away on your birthday, and how to cancel a subscription. Find live deals with prices and list prices, look up store credit-card terms including deferred-interest promotions, and ask whether an Amazon price is worth buying now or waiting on. Every answer includes a link to the Thrifle page it is based on. The data covers 2,250 US retailers, is verified by Thrifle's editors, and each record carries the date it was last checked. The plugin is read-only: it looks things up and never changes anything.
