First off, don't panic, this is normal. 

If you select UPS, there's a decent chance it'll actually ship via Purolator. Why? Purolator has been MUCH more reliable with their delivery speeds and package safety. So don't worry, this is for your benefit with no downside for you. 

A majority of the time UPS Express Saver / Purolator Express will be delivered next day (when placed before 10am CST), however, some addresses will add a day. Also, peak seasons will increase shipping time and couriers will not provide a guaranteed delivery date (Black Friday, Christmas, etc).
