You did not inform us how you stored the oldprice in printfile. Assuming you stored it as a number i.e. 139.02 and not as $139.02, the following should work for you.
Code:
#!/bin/sh

wget -qO- http://cs.actx.edu/~craddock/unix2/lab11 | awk -v oldprice=`cat pricefile` '
    /<b class="price">/ {
    getline
    newprice = substr($0,2) + 0.00

    if (oldprice == newprice) {
        print "The price is the same"
    } else {
        print "The price is not the same"
    }
}'

pac

PAC(8)							      System Manager's Manual							    PAC(8)

NAME

       pac - printer/plotter accounting information

SYNOPSIS

       /usr/sbin/pac [ -Pprinter ] [ -pprice ] [ -s ] [ -r ] [ -c ] [ -m ] [ name ... ]

DESCRIPTION

       Pac  reads  the	printer/plotter  accounting files, accumulating the number of pages (the usual case) or feet (for raster devices) of paper
       consumed by each user, and printing out how much each user consumed in pages or feet and dollars.  If any names are specified, then statis-
       tics are only printed for those users; usually, statistics are printed for every user who has used any paper.

       The  -P	flag causes accounting to be done for the named printer.  Normally, accounting is done for the default printer (site dependent) or
       the value of the environment variable PRINTER is used.

       The -p flag causes the value price to be used for the cost in dollars instead of the default value  of  0.02  or  the  price  specified	in
       /etc/printcap.

       The -c flag causes the output to be sorted by cost; usually the output is sorted alphabetically by name.

       The -r flag reverses the sorting order.

       The  -s	flag causes the accounting information to be summarized on the summary accounting file; this summarization is necessary since on a
       busy system, the accounting file can grow by several lines per day.

       The -m flag causes the host name to be ignored in the accounting file.  This allows for a user on multiple machines  to	have  all  of  his
       printing charges grouped together.

FILES

       /usr/adm/?acct	   raw accounting files
       /usr/adm/?_sum	   summary accounting files
       /etc/printcap	   printer capability data base

SEE ALSO

       printcap(5)

BUGS

       The relationship between the computed price and reality is as yet unknown.
