One more thing, Melissa. Mail,(now from the states) anything you can do without for the first month. Mark the box with WINFLY, The larger the box the harder it is to get it in an airplane, so while it costs more to mail many small boxes they tend to get here faster. The best is to use the big TYVEK Priority mail bags. They are flexible and can be squeezed into small areas.
When mailing just be aware that if weather delays flights, science supplies take a priority over mail. Snowy years can see your mail delayed into November or more. It’s disappointing but weather is fact of life down here and impacts everything. If it happens you say oh well and live with it. Still, it would be the very rarest of years to be delayed that much.
