Woohoo. Did my daily Brickseek search this a.m. and found 1 store was $6 instead of $7.88. Inventory was listed at 351 bags. I called to confirm and was told, by a not-too-bright sounding person, that there were none there, "maybe it's online".
I made the trip anyway and yeah, there looked to be 351 bags stacked chest high on pallets, taking up half the garden center floor. Lol.
