Dear Ms.Amanda Parker,

Thank you for your interest in attending the 63rd annual Southeast Regional SalespersonConference, to be held July 12 through July 14 in the ballroom of the Inter-Regency Hotel.Enclosed is a registration form for you to fill out and send back to reserve a seat.
Please note that the registration cost has increased to $150 from last year’s fee of $120. The change is in response to a sharp rise in registrations last year. If we see the same percentage of increase this year, we will not have enough space to accommodate everyone, so it was felt that the higher fee would keep the number of registrants within reason.
The deadline for registration is June 15. Please have your form postmarked by that date to participate in regular registration.After June 15, an additional fee of $40 will be applied for expedited registration.And, as always, all registration fees include a non-refundable $50 deposit to protect against cancellation.By affixing your signature to the registration form, you agree to abide by these and all other terms governing the Southeast Regional SalespersonConference, which can be found on the back of the form.
Sincerely yours,
Maxine Stinson,Conference Organizer
