Chewy eGift card scam all 50 states

Chewy advertises that you'll receive a FREE $30 gift ecard when you spend $100.  I placed an order for 8 items at 13.44 for a subtotal of 107.52.  When I entered the gift card code "Winter", the subtotal price changed to 137.52.  that would make each item 17.19 each, and $30 higher than the normal price.  They then show a ecard discount of $30.  So you are actually not receiving a 30. gift card.  It's a ploy to get customers to spend $100.  When I removed the discount code Winter, the price lowered to $107.52  Below the offer on the first page, Chewy has an asterisk that certain conditions apply, but they are not available to read on the website.  This is a scam and false advertising.
