Check who actually manufactures the luggage
Three kinds of company use the word supplier and they are not interchangeable: brand owners, the factories that produce for them, and stocklot wholesalers selling whatever they were able to buy this month. Search the category and all three come back on the same page wearing the same word.
It is the first question because it decides what every other answer is worth. A stocklot wholesaler cannot promise you the same product next season, because they do not know what they will be offered. A factory can hold a specification and usually cannot give you a brand. Ask which one you are dealing with, and ask it before price.
Our answer
Carlton is owned by VIP Industries, which manufactures it. We are the commercial partner for that one brand — closest to a distributor — which is what makes a fixed specification, a warranty and an own-label route possible at all.
