I live in the desert southwest, in an apartment with a chiller, so I am at the mercy of my landlord to switch from heat to cool when he demanded it warm enough. it has been around 80° nearly all winter and we are stuck with heat. I am on the top floor and the sun on the roof all afternoon makes it really warm in here. like sweaty warm. my dog was overheating. just everything was melting. got this fan 2 days ago and it's made an incredible difference. it is still warm in here around 4pm, but the air is moving very well throughout the living room and kitchen with it backed up to the open balcony door. in the late afternoon before the sun sets, I close the blinds and set it at the security door and it blows really well, still. very pleased with this purchase. we also have a new dug in the neighborhood that will not stop bathing every second of every minute of every hour it's owner is gone, and on high speed it takes off the to absolute top notes of the bark for my dog's nerves. don't get me wrong, there's nothing that will stop the incredible stress my dug had been under for the last 8 days of this, but at least it's a little better

Walmart member, charged more than non-members

BEWARE! I am a paying Walmart InHome member. I am being charged $2.60 more, for the Lasko Box Fan (Item- Lasko Cool Colors 20" 3-Speed Weather Resistant Box Fan, Black B20301) when logged into my account, than when I view the same page incognito. ( using the exact same URL, I cut and pasted it from one window to the other). I have confirmed this price discrepancy persists even after changing my fulfillment store. This is a clear case of paying members being charged more than public users. I have a side-by-side screenshot and need an executive/tech support contact, to resolve this. The phone reps were unable to help.
