ShopRite complaint: OSTER 6 speed blender Product not available in no stores as advertised, false advertisement

I have inquired and have go to several Shoprite stores looking for the Oster 6 speed blender that is on sale for 9.99 and I was told the product has not been delivered and or they do not have it and it has never come in.

I have asked for a rain check and no one is providing a rain check for a product that has not been received.
Why would you do this, I needed 2 blenders, my son just go his apartment, and it was going to be a gift for him and mine broke, so I needed a new one. I am hoping you can send me a rain check or voucher to get these 2 blenders at the 9.99 price. this was within my budget, since I am going thru some financial hardship. My son and are loyal customer who loves to shop at Shop Rite supermarket, due to their reasonable prices.
My name is Alice Seda, and my address is 98 Carey Street, Mahopac NY 10549 and my number is 917-686-0130. I would appreciate if someone can please get back to me on this. It very important to me.
I thank you for your time
