Answer:
Sentence should end with "every day" not "everyday." Use two words not one.
Step-by-step explanation:
The word "everyday" is an adjective that means every day or all the time or frequent. For example, you have a shirt for special occasions and another shirt you wear every day. You can say "This is my everyday shirt."
In this case, the low prices happen every day, so you don;t use the adjective "everyday." Instead you use the expression "every day."
Incorrect: "We offer low prices everyday."
Correct: "We offer low prices every day."
