Avira – “It is an absolute obligation to check suits for shaatnez when many such items have it.”
How many suits of yours have been found to have shatnez? Your direct acquaintances’ suits? How common is common? These are halakhic shiurim. The last time I asked a competent halakhic authority I was told that for a generic cheap wool suit there is no *obligation* to spend money to check. But for Brooks brothers I was told to spend money to check.
