SWIM is trying to buy 500mg of a research chemical from a website. SWIM wants to know what is your experience with these shipping methods? regular is free and registered is 11.68USD. swim just needs to know if its actually worth spending the 11.68USD
The best thing to do would be to edit your post and take the name out. Also, are you really sweating $11.68? Now I understand. 1st class probably fine.
If you got the money to waste on the chance it will not make it. Then I would go standard post. For the only reason that it would be less likely to be stopped. On the other end. If the company will reship if lost with registered and you want to insure your goods, then spend the extra 12.
Normally I would pick registered but remember you'll have to sign for the package if its registered which is a bit of a drag.
Are you sure the source is legit? Purchased from them before? I'm thinking regular mail would be the way to go.
when i made an order for a known legit vendor, i just went with standard shipping. with express shipping (which costs more) it's more likely to get stopped at customs and can take just as long to arrive. the vendor himself told me that. the benefit of express shipping is that the vendor will reship if you don't receive your package.
