Beedle's Membership Cards

Beedle's Shop, regardless of whether it travels by air, as in Spirit Tracks, or floats on the open ocean, as in and Phantom Hourglass, offers a reward and point system that is managed through Membership Cards, which function to provide complementary services so long as Link remains a loyal, continuous customer. There are different levels of membership Link can attain as incentive to stay buying and selling items to Beedle throughout the entire quest, though all items purchased and sold are replenishable items only, such as Hyoi Pears, Treasures, and Bombs, just to name a few.

Accumulation of Points
Beedle offers Link a Membership with his business that details a reward system for Link if he continues to provide Beedle with consistent patronage. Accepting the Membership offer is free, except in Spirit Tracks, where Beedle charges Link with a down payment of 100 Rupees.

In the three titles, Beedle maintains a point count that stems directly from the amount of items purchased in his store; however, each of the games has a different take on how points are actually accumulated. In The Wind Waker, if Link buys one item, he gains one point towards his Membership; in Phantom Hourglass, each item has a different point value based on its price and type of Membership; and in Spirit Tracks, for every 10 Rupees spent, Link gains one point towards the next Membership. As long as Link buys items in Beedle's Shop, he will continue to accumulate points, but after he has obtained the final membership available, the point system will cease, as nothing further can be acquired through it.

Perks of the Membership Card
The purpose of the Membership is to benefit both parties: As Beedle sees an increase in the purchasing of his products, Link gets price discounts, complementary cards, freebie coupons, and even Treasures in return for his valued patronage. Each membership comes with a different perk, and obviously, as the memberships increase in value, so do the value and significance of the extras that come in conjunction with the Memberships.

The Wind Waker
Once Link makes the required number of purchases, he can pick up the awarded card from any mailbox. Cards can only be used once.

Phantom Hourglass
Each membership level has a corresponding discount. This discount reduces the price of all items in Beedle's Shop, with the exception of Masked Beedle's Shop. As with The Wind Waker, Link may pick up the cards from a mailbox after obtaining the required number of points.

Spirit Tracks
In order to collect shopping points and become eligible for rewards, Link must pay a 100 Rupee fee to buy the Club Card. This card acts as a proof of membership. As with Phantom Hourglass, each membership level has an associated discount, applicable to all items purchased at Beedle's shop.
