1 Wedding invitation costs can range from $1.50 each with do-it-yourself kits from craft stores to $3 or $4 each for mid-range standardized invitations on mid-weight paper to $9 or more each for invitations that use a high-end printing process -- such as engraving or letterpress -- on quality handmade or silk paper. The per-invitation cost goes up with extra folds -- tri-fold costs more than bi-fold -- or lining on the invitations or envelopes. 2  The average couple spends $659 on invitations and reply-cards, according to The Bridal Association of America.
The highest sea-level pressure on Earth occurs in Siberia, where the Siberian High often attains a sea-level pressure above 1050.0 mbar (105.00 kPa, 30.01 inHg), with record highs close to 1085.0 mbar (108.50 kPa, 32.04 inHg).
Very cold air, on the other hand, can create large areas of high pressure because cold air is more dense (heavier) than warm air. The Earth's highest surface air pressures are found in masses of very cold air over places such as Siberia.
