i am very careful with sending my stamps.. not to say i won't make a mistake... i think everyone knows.. that i would immediately correct it.. and then some...
also.. i am very disabled... and i sell little things.. so i can participate... i love listia.. i am homebound.. about 95 percent of the time...lol the other 5 percent is drs...
i think for me... i sell the stamps... then i turn around and buy... and will pay shipping by the seller... for me.. it lets me particpate...
