The rate of a 20 USD Amazon gift card today can vary depending on several factors. One of the main aspects is the current market conditions. If there is high demand for Amazon gift cards, the rate might be more favorable for those looking to purchase or sell them.

In some cases, online marketplaces or peer - to - peer trading platforms could influence the rate. Sellers might set different prices based on their own assessment of the card's value and the competition. Some may offer a more competitive rate to attract buyers, while others might hold out for a better deal.

Moreover, economic factors such as inflation and exchange rates (if applicable in the context of international transactions) can also play a role. A stable economy with low inflation might contribute to a relatively stable rate for the 20 USD Amazon gift card. However, during times of economic uncertainty, rates could fluctuate more significantly.
