Is RePack more expensive than single-use packaging? Yes and no.
Money-wise, single-use does not compare to RePack simply because it is not your regular packaging; it is a full service, which includes packaging cycles, cleaning, prepaid empty global returns, and an integrated reward system.
Single-use packaging is simply a cost, both financially and environmentally. RePack on the other hand saves you money. Offering RePack as an option in the checkout for a fee makes RePack free for you.

(And the real question is, why is single-use packaging so cheap? The answer is quite simple: single-use is cheap because society carries the cost of pollution and waste accumulation.)
