@kimi the $5/$25 should be in the weekly circular. One of my stores has a sign on the gc kiosk promoting the 4x points on Saturdays & Sundays. It’s been a regular thing for a while. It isn’t available to activate until after 12AM on Saturdays and disappears on Sunday nights.
OAN, I recently used 8+ small value rebate gc to buy a Chewy gc to earn 4x points. IDK if there’s a register limit on # of gc the register will accept. Some of the gc were $5 Shaw’s eGC from P&GGE so one can still use store gc to buy 3rd party gc.
