Stacking & Gift Card Plays

Staples.com: $200 digital Visa gift cards with no purchase fee (limit 4)

• Portal/Extension: N/A (retailer offer)
• Source: Frequent Miler
• Link: Frequent Miler
• Rate/Value: $0 purchase fee on $200 gift cards (saves $6.95 typical fee)
• Ends: See source (limited availability)
• What: Staples is waiving the purchase fee on $200 digital Visa gift cards, limit 4 per customer.
• Why it matters: Fee-free Visa gift cards are a key stacking ingredient — buy through a portal (e.g., Rakuten or TopCashback at office supply stores) and pay with a card earning 5x at office supply stores, then use the gift cards at retailers that don't earn bonus otherwise.

Staples.com: $200 Virtual Visa Giftcard For $200 (Limit 4) — Doctor of Credit

• Portal/Extension: N/A (retailer offer)
• Source: Doctor of Credit
• Link: Doctor of Credit
• Rate/Value: $0 purchase fee on $200 gift cards
• Ends: See source
• What: Same Staples offer — $200 fee-free virtual Visa gift cards, limit 4 (terms say 5 but system allows 4).
• Why it matters: Confirmed to code as office supply stores for 5x earning on cards like Chase Ink Business Cash, making this a strong manufactured-spending or gift-card-stacking play.

• Ends: 2026-06-13 (next Saturday)
