We charge $4.99 for standard shipping in the United States, we call it “budget shipping”. Due to the increase of pricing in the US, we’ve had to reevaluate our shipping costs. The price changes based on weight. The price tiers are $4.99 -> $7.99 -> $9.99. The latter is the max shipping costs. Usually you’ll pay that if you’re ordering more than two items.
We use the United States Postal Service for shipping.
