I also placed an order on March 5th. I called this morning, and the customer rep said that I am supposed to receive the e-mail giftcard around May 1st.
I placed an order during the last gift card promo (Spend Some, Get Some or GET2GET) where you get double gift card value when your regular price purchase includes both women's apparel and a shoe/bag purchase (pretty much exactly like the one newmommy_va just posted).
My order was placed March 5, and by my calculations, it was 8 weeks yesterday, so I should've received the gift card by now. Have other people who purchased during that promo received their GCs? Is NM usually late in sending out the GCs?
