Look at the products. It's all stuff that was released in early 2023 or 2022, or before.
No new macbook pros, no new imac, no iphone 15, etc.
They're just clearing out inventory of stuff that will get refreshed in 6 months.
Mostly but not all. Apple Watch Series 9 is included ($50 gift card) yet it only came out two months ago.
The 15 inch MBA was also introduced in June 23.
Looks more like the GC are on holiday present type items.
