Received an email from Sam's club:
Email Subject - "Incoming: $50.00 eGift card!"
1. $10 egift card when you try scan & go shopping
2. $20 egift card with your first $40+ online purchase
3. $20 egift card when you try curbside pickup
I became a Sam's club member last month with the $45 GC deal, since then I didn't make any purchase, that's why may be I got these offers. YMMY.
