Get insurance when you mail it. I have never had a wet package ever, so that's not common- most packages are paper/cardboard remember. Just mail it in an envelope or box that can't bend. You can put extra cardboard in the package or mount the print on something very firm.
No point in insurance. I don't know what he is selling his product at but i'm sure It's a relatively high profit margin. If it gets damaged mail out a new one chances of it getting damaged are quite slim. So no point of eating away at a profit margin for something that has a 1/100 chance of happening. really though i'd recommend the envelope way. You can even stiffen up the envelope by cutting out a piece of a cereal box (very thin cardboard). Then put that and the print in there and put a 49 cent stamp on it and ship it off. Chances are very slim it'll bend since the envelope only comes into contact with 2 or 4 people the rest is machines that are calibrated not to bend envelopes. As I said i send vinyl decals this way out of 50+ sales i've had no complaints about shipping damage.
Not trying to tell you what to do i'm just telling you what works for me. It'll definitely work for paper if it works for vinyl. Just trying to help you save on shipping also you can ship envelopes to basically any major country for $1.20 that is if you're in the states.
He was worried about damage so i assumed he was worried about losing the product. Look, anyone can go the cheap route and skip the extra fees but i've lost about $120 in the mail, about 2 $60 things i mailed out before i learned my lesson. You're right it doesn't always make sense to get every protection but for USPS they've made priority mail pricing so that many times it costs only slightly more or the same as mailing it another way...it will vary by location, size, etc. though. I just checked the price for priority flat cardboard envelopes and they're all about $6...to me that's pretty normal shipping cost...and you get tracking and insurance with priority. The only actually cheap shipping for packages that i know of is first class mail for small bubble envelopes...it's like $2.30 but that's with no tracking, no insurance, and if you have to get the label at the post office you can only do it at the counter and not the automated machines. I don't know what the situation is for OP's sales, but this is all just information to consider.
