2011 Topps Series One

I'm not even sure where these came from, which is a little annoying because I like to know the pedigree of packs opened. I have opened 12 card, 10 card and 8 card versions of 2011 Topps Series One but not 5 card packs.
I have all the Series One Red Sox, but I am still in the hunt for Kimball Champions. I have a feeling that these will not contain any inserts but just five base cards.
The Red Sox available from Series One were:
#3 Jon Lester
#62 Jonathan Papelbon
#115 Jason Varitek
#123 Mike Lowell
#208 Clay Buchholz
#218 Victor Martinez
#254 Lars Anderson RC
#278 Marco Scutaro
#302 Adrian Beltre
#314 Ryan Kalish
#315 David Ortiz
#324 Boston Red Sox TC

5 card pack 1:

#227 Nate McLouth Braves

#235 LL Hernandez, Buchholz Red Sox , Price

#289 Yuniesky Betancourt Royals

#297 Jason Jaramillo Pirates

#322 Brent Morel White Sox

5 card pack 2:

#234 Miguel Montero D-backs

#249 Aaron Harang Reds

#261 Alexel Ramirez White Sox

#273 Derrek Lee Braves

#304 Jim Thome Twins

Correct, only base. Were these 5 card packs a retail 99p product? I remember seeing $2.99 on other packs.
