I know this is a question that when you are first learning to coupon comes up, What is the difference between trial size and travel size? Well there is no difference, they are the same size and when couponing and your coupon says any you can use that coupon on it. However if it says excludes trial sizes, that means it can not be used on trial sizes (or the ones that are marketed as travel sized)
It is marketing to label the trial sizes as travel sizes. They are the sizes that when you are traveling fit great in your bag and they are for convince which is why they market them that way but when it comes to couponing they are the same. So even if it is in the “Travel” section and the coupon you have says excludes trial size you can not use that coupon on the “travel” sized ones.
