Why does the gift card code match the payment amount on my site?

Dear Shopify Team,

I hope this message finds you well. I would like to express my gratitude in advance for your assistance in resolving my query.

I have encountered an issue while creating gift cards as products to sell on my website. Specifically, (I have set different denominations for the gift cards, such as 200 AED), with a price of 150 AED. However, when I conducted a test payment, both the payment amount and the gift card code were 150 AED. This discrepancy has left me puzzled.

It seems as though we are applying a discount, allowing customers to pay less and receive more. However, in this case, it appears that customers are receiving exactly what they pay for.

I hope I have clearly conveyed my question. I kindly request your assistance in resolving this matter.

Thank you once again for your support.

Best regards,
