hi Luck,

Thanks for your kind message. Your question is very good one. It seems that $15 is the acceptable amount for an order on Amazon. You should add more other products or increase the quantity to reach this amount.

Please kindly find out our feedback on your question and also other Amazon deals & sales programs: https://forbabycare.com/amazon-sales-and-deals/explanation-on-amazon-sales-deals-programs/2017.

By the way I’ve updated accordingly the article. Thanks for your constructive feedback!
