Q.
How are coins during campaigns calculated?

A.

Granted coins are calculated based on the purchase amount (excluding tax) times the coin-back rate which is set according to each campaign.

Here are some examples when purchasing together multiple eBooks eligible for multiple coin-back campaigns, and your membership rank is regular (coin-back rate = 5%).

*When you purchase eBooks which have the same coin-back rate and coin expiration date together in one settlement, the coin-back rate is calculated based on the total amount of these eBooks (excluding tax).

 

(1) If eBooks A, B, C, D are all not eligible for the campaign


⇒ (eBook A + eBook B + eBook C + eBook D) x 5%

 

(2) If the eligible coin-back campaign differs according to each eBook


  • eBooks A + C: Eligible for Campaign X (30% coin-back / store-wide campaign), as well as Campaign Y (20% coin-back / individual campaign)
  • eBook B: Not eligible for any campaigns (will only get coin-backs based on member rank)
  • eBook D: Eligible for Campaign Z (10% coin-back / individual campaign)

 
⇒ (eBook A + eBook C) x (30 + 20)% + eBook B x 5% + eBook D x (5 + 10)%

*For Campaign Y (20% coin-back / individual campaign), you will not receive coin-back based on your membership rank as the eligible eBook is also eligible for Campaign X (30% coin-back / store-wide campaign), which does not give coin-backs for membership rank.

 

(3) If the eligible coin-back campaign differs according to each eBook, and is also target of the “50% Coin Back for First-time Purchasers” campaign


  • eBooks A + C: Eligible for Campaign X (30% coin-back / store-wide campaign), as well as Campaign Y (20% reduction / individual campaign)
  • eBook B: Not eligible for campaign (will only get coin-backs based on member rank)
  • eBook D: Eligible for Campaign Z (10% coin-back, individual campaign)

 
⇒ (eBook A + eBook C) × (30 + 20 + 50)% + eBook B × (5 + 50)% + eBook D × (5 + 10 + 50)%

*For Campaign Y (20% coin-back / individual campaign), you will not receive coin-back based on your membership rank as the eligible eBook is also eligible for Campaign X (30% coin-back / store-wide campaign), which does not give coin-backs for membership rank.

 

Notes


  • Please note that Campaign Coin will not be granted in case of coupon usage.
  • If coin calculation includes decimals (less than 1 coin), it will be truncated.
  • If the amount of granted coins exceeds the purchase amount excluding tax (granted more than 100%), it will be adjusted so that it would be less than 100%.
  • Coins basically expire at the end of 5 months from the eBook’s purchase date, but coins granted through the “50% Coin Back for First-time Purchasers” campaign expires at the end of the following month after your initial purchase. Please check each campaign page for the coin expiration date for other campaigns, as it may differ based on each campaign.
  • Please refer to the BOOK☆WALKER Coin page for more details about coins.
