If the returned product allowed for a credit of a certain amount to your Club Printemps Wallet, you will be reimbursed for price of the item, and the amount that was credited to your Club Printemps Wallet will be deducted from it.

If the amount available in your Club Printemps Walle is less than the amount credited and spent, you will be reimbursed the difference between the item and the amount credited which was not able to be deducted from your Club Printemps Wallet. 

Example:

Day 1: I start my 10% Shopping Day and make a purchase totalling 1000€ allowing me to credit 100€ to my Club Printemps Wallet the next day

Day 2: I spend a part of my Club Printemps Wallet balance for a new purchase. The balance of my Club Printemps Wallet now amounts to 80€

Day 3: I would like to be reimbursed for my 1000€ purchase from Day 1. We deduct 80€ from my balance and I am reimbursed 980€ (1000€ - 20€ which was credited to my Club Printemps Wallet after my initial purchase but which was not deducted upon reimbursement)
