A: This is no longer correct. It only works for new customers and only 1 card per account. existing members are out of luck and cannot use them. You can create new accounts for each gift card if you are a current member.
A: It works for new and existing members. I would not recommend for new members because you can't use any promo discounts when paying with this card.
A: For current HelloFresh pricing in my area, the $60 gift card will almost cover a meal plan for 2 people and 3 meals for a week (total $62.93; shipping is $8.99; meal plan is $53.94). The $51 is what you pay when there is a Target promotion (15% off), but you get $60 applied to your HelloFresh account. However, you cannot apply any promo codes to an order if you are using the $60 gift card, so not really a good value for first time users since you can easily find promo codes for $70+ on your first order.
