    I have just noticed an issue with my cart for low weight items. When the total units in an order reaches 0.3, the First Class shipping option disappears, when it shouldn't disappear until it reaches around 0.8 units (13oz).
    (My units are in pounds)

    For example, for this page the first product has a unit value of 0.1
    First Class works fine for one or 2 items bought, but as soon as it hits 3 items, it is treating it as though the weight is too high.

    I've used this for several years now and only recently noticed this issue. Has something changed with units? Or advance shipping?

    The cutover seems to be between 2.18 and 2.19 as the qty in the cart.. But up to there the prices look constant. 3 for First class, 6.70 priority, etc.. So I'm not sure it's working fine at low levels.

    Maybe Mal can help. I don't use USPS or the calculators.

    Some shipping help documents are available at

    Thanks JV.

    I emailed Mal and apparently USPS changed the set up a while ago, so now in Advanced Shipping, First Class has 2 options:

    First Class - for envelopes, up to 3.5oz
    First Class Parcel - for packages, up to 13oz.

    I changed my set up to FC Parcel and everything is working again.
